By being able to perform any physical exercises or yoga asana poses that requires certain skills, stamina, strength and flexibility doesn't guarantee us to be free from ignorance, unhappiness or suffering, nor will guarantee us unconditional peace and compassion.
Unconditional peace and compassion that derives from realization of the truth and be free from egoism and attachment, is not determined by the conditions and abilities of the physical body to do this or that.
Yoga practice of letting go of the egoism, attachment, identification, craving and aversion, requires great patience, determination, perseverance, tolerance, forbearance, acceptance, adjustment, adaptation, accommodation, non-judgment, non-comparison and non-expectation. Throughout the journey towards the realization of the truth or selflessness, there's no judgment, comparison nor expectation. Just keep practice, without intention nor expectation, and allow the result or the fruit of our actions / yoga practice / duties and responsibilities to be what it is, as it is.
In the process of practicing any yoga asana poses, in order to be able to come into any of the poses effortlessly without struggle, we need to be patient, be determined, be persevered, be tolerant, be able to forbear any discomforts physically, mentally and emotionally, be able to adjust ourselves to adapt and accommodate the practice under any circumstances, conditions or situations, be able to accept the body and the mind as they are from moment to moment while allowing changes or improvement to be happening naturally as it is, allow the physical body and the mind to develop all the requirements that allow the body to come into the yoga poses effortlessly without struggle, without giving up, without judgment, comparison, expectation nor intention, and allow the result or the fruit of the actions / yoga asana practice to be what it is, to be there as it is.
In the process of performing all these yoga asana practice, it is not about achieving certain results or attaining certain benefits from the practice, nor it's about to look good and feel good about ourselves (the ego), to boost self-esteem or self-confidence, nor strengthening the egoism, identification and attachment towards the qualities of names and forms, but we should be letting go of the egoism, letting go of identification and attachment towards the impermanent conditions and abilities of the body and the mind, letting go of attachment towards any qualities of names and forms, letting go of attachment towards the egoistic likes and dislikes, agreements and disagreements, craving and aversion, judgments, comparisons, expectations, intentions, and eventually be free from being disturbed, or affected, or influenced, or determined by the qualities of names and forms, or the result of our actions, and be free from impurities of anger, hatred, jealousy, greed, dissatisfaction, disappointment, feelings of hurt, guilt and regrets, pride, arrogance, agitation, depression, fear and worry.
When the mind is free from egoism, attachment, craving, aversion, and impurities, the mind is able to perceive the truth of everything as it is, uncontaminated, uninfluenced, undetermined by impurities that arise due to egoistic reactions towards the perception of names and forms based on what the mind believes what things are, under the influence of incorrect information, thinking, beliefs, judgment, imagination, projection, likes and dislikes, agreements and disagreements, craving and aversion. And this allows us to realize unconditional peace and compassion.
Even if our physical body is in good conditions, being strong and flexible, and is able to perform all the yoga asana poses perfectly and beautifully, but if we don't know what is letting go of the egoism, identification, attachment, selfish desires, intentions and expectations, craving and aversion, then we will still be affected, disturbed, influenced and determined by impurities of anger, hatred, jealousy, greed, dissatisfaction, disappointment, feelings of hurt, guilt and regrets, pride, arrogance, agitation, depression, fear and worry coming from the egoistic reactions towards the objects of the senses (qualities of names and forms) perceived by the mind through the eyes, ears, nose, tongue, body and thinking faculty. The mind is constantly being in a state of restlessness, and have no peace nor be compassionate towards oneself or others.
