In the teachings of yoga, all kinds of teachings and practice served the purpose of enabling the selfless perceptive cognitive intellectual emotional thinking and acting mind to be free from the idea of 'I', ignorance, egoism, impurities and restlessness, to realize the truth of selflessness and impermanence, to know itself, and thus, be free from the suffering deriving from ignorance and its by-products.
That transformative process is being referred as self-transformation or self-evolution, however, the mind is still the same mind, it doesn't change into something else that it is not, even having under going many transformational modifications or changes. The mind might be thinking, understanding, feeling, desiring, behaving, acting and reacting differently from before, the states of the mind is never the same from moment to moment, the modifications of the mind is constantly changing, but it is still the same selfless mind existing and functioning selflessly and momentarily under the selfless impermanent existence and function of the same selfless physical body that is constantly changing, where the selfless physical body is not the same appearance or condition from moment to moment, but it is still the same selfless physical body.
There's neither right nor wrong when the different minds understand that "It's not the same body (in terms of appearance and condition) and mind (in terms of the states of mind and behavior pattern) every moment because of selfless impermanent changes" and "It's still the same body and mind even though it's under going ceaseless selfless impermanent changes, transforming into different physical appearance and condition, and transitioning in different states of the mind and behavior pattern, from the moment it exists until it ceased existing." Both are equally correct under different points of view. It's nothing contradicting at all. But regardless of the different understanding due to the different points of view, the body and mind is selfless and impermanent is the inevitable truth, where there is no permanent independent individual infinite existence of 'I' existing in the selfless impermanent mortal body and mind that is constantly changing, decaying and disintegrating.
The car is still the same car, even if it's under going ceaseless impermanent changes of decaying, and eventually, it will be retired and ceased functioning, where the exterior appearance and the interior compartments and decorations, might have been being modified or replaced in countless times that it is not the 'same' car every moment, even if it has been going through changing owners and/or registration plate number.
Some minds might be confused towards how come the mind is still what it is, that the mind is still the same mind, even when it is under going all kinds of practice to be modifying itself, experiencing self-transformation, and attaining self-realization? Such as quite many 'buddhists' would think that one will become a 'buddha' upon enlightenment, where 'buddha' is someone or something that is superior, being separated or distinct from an inferior mind, or person, or living being that is ignorant, selfish, evil, greedy and impure.
One doesn't perform certain practices and become a 'buddha', or one doesn't become 'selfless' and 'compassionate'. All and everything are 'buddha', all are selfless and compassionate, regardless of whether one performs or doesn't perform certain practices, knows or doesn't know that, realizes or doesn't realize that, and attaining enlightenment, or not.
No doubt that there are certain gross and subtle changes or transformations happening to the selfless function, or modification, or state of the mind, while the mind is performing certain practices that served the purpose of disciplining the mind, purifying the mind and quieting the mind, in order to be eliminating the idea of 'I', ignorance, egoism, impurities and restlessness.
However, the mind is still the same mind, it is still what it is, being selfless and impermanent, it doesn't change into something else that is not what it is, regardless of whether all these modifications, changes or transformations are happening, or not.
The only difference is, when this selfless mind is functioning under the veil of ignorance and its by-products, it doesn't know or doesn't understand itself, or what is going on in itself, or why it perceives suffering, or what is suffering, or what is the cause of suffering, and hence, it might think, reason, understand, feel, desire, behave, act and react in the way that hurt itself and others and the surrounding environment due to being ignorant, or it is functioning under the influence of the veil of ignorance and its by-products.
Upon the annihilation of the veil of ignorance and its by-products, or upon self-realization towards the selflessness and impermanence in itself and in all kinds of perceived names and forms, of knowing Thyself, of knowing the truth of names and forms, the mind wouldn't be thinking, reasoning, understanding, feeling, behaving, acting and reacting in the way that hurt itself, or others, or the surrounding environment.
The selfless existence and function of the selfless mind and the selfless physical body doesn't change into something else. It doesn't become selfless. It is selfless, regardless of whether the mind knows or doesn't know about it's existence and function is selfless. It doesn't change and become something permanent, or immortal, or infinite. It is either being restless, or being less restless and more quiet, or resting in silence, during its selfless impermanent existence and function. It is the same selfless and impermanent before, during and after the transformation and upon self-realization, even though it keeps under going ceaseless selfless impermanent changes or transformations until it ceased functioning and ceased existing.
Selflessness isn't something saintly, sacred or mystical. Selflessness is not something to be attained and becoming. Selflessness doesn't only present in the enlightened buddhas, gurus, saints and sages, or is absent in the non-enlightened ignorant, selfish, impure and suffering beings. Selflessness in not about unselfishness. Selflessness is not the opposite of selfishness. All and everything don't attain selflessness and become selfless. All and everything are selfless, regardless of what.
Selflessness is there is no existence of an individual permanent independent existence of 'I' in all kinds of selfless impermanent names and forms.
It's whether the mind realized selflessness under the absence of the idea of 'I' and ignorance, or hasn't realized selflessness under the presence of the idea of 'I' and ignorance.
And thus, "All and everything is dhamma. All and everything are buddha." - Siddhartha Gautama Buddha
Void of 'I'.
Void of grasping.
Void of desire.
Void of ignorance.
Void of suffering.
Void of restlessness.
There's neither past nor future, there's only now.
It's merely selfless impermanent names and forms arising, changing and passing away, inter-depending and inter-influencing among one another selflessly, governed by cause and effect, influenced by actions and consequences of actions, under the support and influence of different selfless elements and selfless energy that are also inter-depending and inter-influencing one another selflessly.
All these different terms are one.
Dhamma, or the truth of selflessness and impermanence, is neither sacred nor non-sacred. It is what it is. It is what all and everything are. It cannot be changed, be contaminated, be hurt, be disrespected, be humiliated, be offended, or be destroyed.
Regardless of the absence and presence of ignorance, the different degrees of ignorance, the different types and degrees of suffering, the different states of mind of interchanging in different realms, the different qualities of different names and forms, the different thinking, beliefs, understanding, desires, behaviors, actions and reactions, and the different consequences of all that, all and everyone and everything is selfless and impermanent.
What doesn't change, that is permanent, that is infinite, that is timeless, is the truth of selflessness and impermanence.
Because all are selfless, there's not a permanent independent infinite 'I' existing to be identifying as "I am this" or "I am that", or "I am neither this nor that", or "I am under going selfless impermanent changes", or "I am under going the infinite restless loop of ceaseless births and deaths", or "I need to be free from all that". It doesn't mean that all these don't exist, or there's no selfless impermanent changes, or there's no restless ceaseless births and deaths, or there's no perception of suffering deriving from being ignorant.
The selfless physical body that comes with the selfless thinking and acting faculty exists selflessly and momentarily. All kinds of selfless names and forms exist selflessly and momentarily. The selfless impermanent changes are happening ceaselessly. The ones that are under going restless ceaseless births and deaths is every single selfless neutron, cell and atom in the selfless physical body, and every single selfless thought arising, changing and passing away in the selfless modification of the selfless mind. The different realms are the different states of the mind. The one that is transitioning in between the different realms is the selfless thinking faculty. Cause and effect exists. Actions and consequences of actions exists.
The one that performs actions through the selfless organs of actions, and either enjoying or suffering for the consequences of actions, that affects the selfless physical body and the selfless states of the mind in certain way, is the selfless thinking faculty. The one that is happy or unhappy, kind or unkind, ignorant or wise, selfish or unselfish, is the selfless thinking faculty.
The one that is not free, that is restless, that is in painful sorrow and suffering, being bound by selfless impermanent changes governed by cause and effect, influenced by actions and consequences of actions, as well as perceiving or experiencing suffering deriving from ignorance, is the selfless thinking faculty functioning under the presence of the veil of ignorance and its by-products.
The one that has intense yearning towards liberation, that has certain degrees of awareness and will power/freewill to be performing certain practices to be free from all that, is the selfless thinking faculty.
The one that can free the selfless thinking faculty from ignorance, is the selfless thinking faculty itself.
It's not even "I am selfless", or "I am That, which is selfless, infinite, unlimited, unconditional, beginningless, endless, birthless, deathless, timeless and changeless," as even That, is also selfless, that doesn't belong to anyone or anything, that doesn't possess or own anything, that doesn't control anything, but all and everything are arising, changing and passing away upon it, under their own cause and effect.
If something that exists infinitely is not selfless, is something sentient, that has been witnessing all kinds of names and forms arising, changing and passing away governed by cause and effect, and witnessing all kinds of painful sorrow and suffering in all kinds of
sentient living beings functioning under the veil of ignorance, then that is the greatest suffering in the entire universe of all time, as that is permanent and infinite.
Just as the selfless physical body doesn't exist or function without the selfless neutrons, cells and atoms forming the entire complex selfless physical body with the function of the selfless thinking faculty, supported by the selfless elements and selfless energy, where all these are inter-depending and inter-influencing among one another to be what they are. While each selfless element, energy, neutron, cell or atom doesn't belong to the selfless physical body, and vice versa. Each selfless element, energy, neutron, cell or atom doesn't have an existence of 'I' to be identifying as "I am element/energy/neutron/cell/atom" or with the selfless physical body. And the selfless physical body doesn't have an existence of 'I' to be identifying with the selfless elements, energy, neutrons, cells and atoms.
Go beyond all kinds of identifications. Go beyond "I am That", "I am infinite", "I am all compassionate", "I am all wise", "I am all powerful", "I am all existence", "I am all knowledge", "I am strong", "I am positive", "I am happiness", and so on.
What is selfless, it doesn't have an existence of 'I' to be what it is, to be identifying with anything, to be possessing/owning anything, or to be belonging to anything.
