All minds are selfless, and all selfless minds are having their own particular unique modification of the mind that is selfless, impermanent, limited, conditional, and non-self, even if there are certain cross-similarities among the many different minds.
Even within the one same particular ancestry lineage, family, and community, sharing the one same similar genetic inheritance, where the minds are growing up being surrounded and conditioned by the one same particular traditional or non-traditional family/communal/tribal/cultural/spiritual/religious/political/national/regional/philosophical/educational/commercial ideas, beliefs, values, practices, and visions, that influence the mind to have a particular way of thinking and reasoning, way of doing things, way of living and interacting, and way of conduct, that give rise to particular reasoning and understanding, agreements and disagreements, and desires and don't desires, that influence the different behaviors or actions and reactions in certain way, but then, each mind also has their own particular unique modification of the mind undergoing specific conscious evolution, that influence and determine the different states of mind that impact oneself and others and the surrounding environment differently in certain way and not in certain way, not to say, among the many different minds that are being conditioned by the many different traditional or non-traditional ideas, beliefs, values, practices, and visions, where each mind has their own particular unique personality and characteristic, life experiences and learning process, reasoning and understanding, agreements and disagreements, and desires/don't desires, that are all impermanent, limited, and conditional, that lead to different conscious and unconscious evolution/transformation/changes/outcomes.
Even more importantly, all minds can have their own unique mind thinking and behavior pattern evolving from the existing particular conditional thinking and behavior pattern that was/has been being conditioned by any particular ideas, beliefs, values, practices, and visions, where each mind has or can develop and empower different degrees of patience, acceptance, initiation, determination, perseverance, forbearance, willpower, tolerance, accommodation, adaptation, adjustment, decisiveness, self-introspection, and/or self-control, where there are different unique life experiences and learning processes under the presence of different conditions, situations, ties and connections, relationships, interactions, and activities, that give rise to different knowledge that influence the intellectual reasoning and understanding, that give rise to different agreements and disagreements, desires and don't desires, that influence the different behaviors, actions, and reactions, that impact oneself and others and the surrounding environment in certain way or not in certain way.
Because all THAT, not only that they are all selfless and non-self, but more importantly, they all are impermanent, limited, and conditional, that are ceaselessly changing being influenced and determined by the existing internal and external conditions and situations that are also impermanent, limited, and conditional. And the presence of conscious awareness/freewill/effort/action/activity under the state of consciousness and semi-consciousness can be influencing all that in certain way or not in certain way, either constructively or destructively, depending on the existing different understanding and desires and don't desires.
The mind that knows and understands this, is fearless and in peace, regardless of what is happening internally in the body and mind, and externally in the surrounding environment of a world that doesn't belong to anyone or anything.
Such mind doesn't desire to be controlling or expecting anyone or anything to be in certain way or not in certain way, but might or might not be making use of the selfless impermanent limited and conditional momentary life existence and function of the mortal body and mind to be performing possible selfless actions within one's ability and limitation, that would benefit oneself and others and the surrounding environment, devoid of the idea of 'I' and egoism, not being determined by the actions and the consequences/fruits/outcomes of actions.
"Performing selfless actions without grasping, while allowing and respecting the fruit of actions being what it is, as it is, and it is impermanent," is the essence of the teachings and practice of yoga and/or buddhism.
The minds that have been coming in contact with such knowledge through reading or hearing, while thinking and believing that they know and understand this, but not really (haven't attained direct self realization yet), they are being determined by the internal and external impermanent changes/conditions/situations, and are being over-powered by the instinctive urge of controlling all and everything to be in certain way and not in certain way, being the slave of the boundless and endless conscious desires of craving and aversion, and being over-powered by selfishness, possessiveness, defensiveness, greed, dissatisfaction, discontentment, fear, the sense of pride and shame, the sense of high and low self-esteem and self-worth, the sense of goodness and badness, righteousness and wrongfulness, meaningfulness and meaninglessness, positiveness and negativeness, auspiciousness and inauspiciousness, togetherness and separateness, happiness and unhappiness, joyfulness and joylessness, pleasantness and unpleasantness, accomplishment and non-accomplishment, success and failure, gain and loss, of all kinds of duality, as well as being over-powered by the sense of boredom, loneliness, emptiness, left-out, unloved, unnoticed, unattended, unrecognized, unsupported, disliked, disapproval, disagreed, disrespected, humiliated, belittled, offended, victimized, depressed, oppressed, lack of freedom, absence of freedom, absence of peace, desperation, painful sorrow, physical pain/discomfort/weakness/injury/illness/aging/decaying, mental and emotional pain/discomfort/shortcoming/hurt/disturbance, of all kinds of physical and mental/emotional suffering. Such mind is restless and peaceless.
Out of restlessness and peacelessness (violent perturbed state of mind), or under the influence of all kinds of unpleasant undesirable impurities or painful suffering, many minds that don't know and/or don't understand towards what is going on in themselves (not knowing Thyself), would behave, act, and react in the way that hurt oneself and others and the surrounding environment, in order to express as well as to relieve such disturbing painful suffering state of mind.
More importantly, all minds under the presence of conscious awareness and cognition to be perceiving and recognizing pain and pleasure/enjoyment and suffering, regardless of who/what/where/how/when, can be free from all that, out of their own conscious freewill, initiative, effort, intense yearning towards liberation/absolute knowledge/unconditional peace, determination, and perseverance.
The uncontaminated genuine yoga and/or buddhism teachings and practice is all about the annihilation of the veil of ignorance that is naturally formed upon the rise of the idea of 'I' (the ego), egoism, impurities, and restlessness in the selfless impermanent limited and conditional modification of the mind under the presence of conscious and semi-conscious awareness, that are all non-self, that doesn't even belong to the mind (the selfless perceptive cognitive intellectual emotional thinking and acting faculty/mechanism that is part of the many different selfless mechanisms/functions/organs/systems of the selfless physical structure of the selfless conscious sentient living organisms) itself, where the mind sees or knows itself upon the annihilation of the veil of ignorance, and realizes unconditional peace, where the mind stops hurting itself and others and the surrounding environment under the presence of absolute knowledge (wisdom) and unconditional peace.
The yoga and/or buddhism practice of performing different practices that suit different minds accordingly, is all about activating the conscious mind evolution process of purifying/quieting/silencing the restless impure egoistic modification of the mind, by developing the basic essential foundation of mental and emotional independence while thinning-out and eliminating the idea of 'I' (the ego), egoism, impurities, and restlessness, via the observation of dispassion, renunciation, solitude, seclusion, non-grasping/non-attachment/non-clinging, non-craving, non-aversion, non-association, non-identification, non-comparison, non-judgment, non-expectation, concentration and meditation, and the practice of silence (Mauna), preparing the mind for performing self-inquiry under an open-mind that is free from the influence of any particular worldly egoistic ideas/beliefs/values/practices/visions, to be inquiring towards the truth of everything that the mind comes in contact with/learns/experiences/sees/hears/reads/being told by some others, especially towards realizing or knowing Thyself, knowing and understanding what is going on in the modification of the mind, of knowing what is the 'I' or the self acknowledgment under the presence of the conscious awareness/perception/cognition that the thinking mind/faculty perceives, thinks, believes, acknowledges, recognizes, identifies, and asserts as 'I', or 'myself', or 'mine' that belongs to 'I' or 'myself', that there is the wishful thinking in the selfless mind would like to think and believe that itself is or has a solid permanent independent infinite immortal individual self existence/identity of an unique individual consciousness/soul/spirit/being, that is devoid of any kind of suffering or limitation, but somehow, it is unwittingly residing/being trapped in the finite mortal impure physical body, that is full of all kinds of suffering and limitation.
Due to such ignorance, the selfless mind is in a state of suffering, or peacelessness, or not free, and there is a natural spontaneous desire to regain or return to that 'suffering free infinite immortal status/identity' that it wants to believe that it is all true, that it really exists, that it really has, and that is what it really is (what many minds would like to think and believe that itself is the existence of an infinite unlimited unconditional immortal existence of 'who I really am', that is super powerful - omnipresence, omniscience, and omnipotent, or Shat-Chid-Ananda - infinite existence, all knowledge, and absolute bliss), that belongs to itself.
The one that is or wants to be identifying with something or anything, is the selfless continuous stream of thinking/thought in the selfless impermanent limited and conditional modification of the conscious perceptive cognitive intellectual emotional thinking and acting mind.
The selfless impermanent limited and conditional existence and function of the perceptive cognitive intellectual emotional thinking and acting mind is not the all pervading timeless attributeless selfless universal consciousness that doesn't belong to anyone or anything, that gives rise to the selfless conscious and semi-conscious awareness to the different selfless minds that are functioning consciously under the states of consciousness and semi-consciousness.
That is why the silence/annihilation/cessation of the restless egoistic impure modification of the mind or the restless thought current, devoid of the idea of 'I', egoism, impurities, and restless thought activities, where the selfless mind is absorbed into or resting upon the all pervading timeless attributeless selfless universal consciousness, is the core as well as the only objective of the teachings and practice of yoga and/or buddhism, to know Thyself, that is not about to know who I really am, but to realize the truth of selflessness and non-self in the selfless impermanent limited and conditional mind, the veil of ignorance and the by-products of ignorance, the knower and the knowledge, the experiencer and the experiences, the action performer and the actions and the consequences of actions, the one that enjoys and/or suffers, the practitioner and the practice, the observer and the observation, the inquirer and the inquiry, the realization, the liberation, and the peace, and so on. All are selfless and non-self.
The yoga and/or buddhism observation or practice that is in accordance to the uncontaminated genuine teachings or dhamma, and that is being observed or practiced as it is, can allow the selfless mind to realize the truth of selflessness and non-self, where all and everything including the existence and function of itself, is selfless, where there isn't any solid permanent independent infinite immortal individual self existence/identity existing to be undergoing the selfless formation (birth, or the beginning of existence and functioning), impermanent changes of growth, ceased growing, decay, and disintegration, or decomposing, or passing away (death, or ceased functioning and the end of existence), and all these selfless manifestations are non-self, where the selfless manifestation of formation/existence/functions/changes/decay/disintegration/decomposition/ceased existence in all kinds of names and forms, don't even belong to the names and forms themselves.
Due to the different minds are being conditioned by the different ideas, beliefs, values, practices, ways of thinking, ways of doing things, ways of conduct/behavior/action/reaction, that give rise to different reasoning and understanding, that is influencing the different desires and don't desires in the different minds, it is common and natural that there are many disagreements, arguments, debates, dissatisfaction, and frustration existing among the different minds that are trying to convince one another about what and who is right or wrong, or who and what is more true/accurate than the other. But that not only doesn't lead the mind towards silence that gives rise to correct understanding, or wisdom, or absolute knowledge, but it is augmenting, stimulating, and agitating the restless egoistic impure modification of the mind even more, fueling and empowering the veil of ignorance.
That is why there is the highly practical and essential initial basic observation of forgoing/abandoning/refraining from all kinds of habitual egoistic activities of small talk, big talk, vain talk, boasting, glorifying, story telling, justification, gossiping, slandering, blaming, finger pointing, condemning, criticizing, argument, debate, discussion, interaction, or communication.
Inquire the truth of everything, including all that is here, and all and everything that the mind has been coming in contact with since birth, of all kinds of information/inputs/ideas/beliefs/values/practices/inspirations/aspirations coming from everyone and everywhere.
