Some yoga enthusiasts are not free from self-righteousness where they think and believe that self-righteousness is a good and upright quality that compliment their yoga practice.
Due to deep rooted ignorance and egoism, there are minds that think and believe that they are good and righteous people and seeing themselves are somehow better human beings than some others whom they perceive as bad and wrongful human beings, and for the sake of humanity, they should stand up for righteousness and condemn those who think and behave in the way that is against what they think and believe is good and rightful way of thinking and behavior, that is bad and wrong, based on their understanding and expectation towards how people or human beings should or shouldn’t behave.
None can ‘tell’ or ‘teach’ another being/person/mind/community about “This is right and that is wrong.” as there’s neither right nor wrong, but just different minds judging everything differently based on their own particular thinking, belief, values, practice and preferences, and to behave, act and react in certain way. Siddhartha Gautama Buddha never said or taught about “This is right and that is wrong.” even though there’s the Eight Fold Path observations for the mind to purify and silent itself to allow the mind to inquire the truth of everything, to see things as they are, beyond the limited/conditioned judgment under the influence of different egoistic worldly thinking and beliefs.
It has to come from the mind itself to inquire into the truth of self-righteousness, where it doesn’t exist in selflessness, namelessness, formlessness, attributelessness.
Just as the ideas of patriotism, loyalty, family ties, friendship, relationship, connection, society, community, country, nationality, pride/shame, deserving/undeserving, meaningfulness/meaninglessness, or positiveness/negativeness, are all part of the play of the ego and egoism derived from ignorance. The mind only knows what it knows and what it thinks and believes about what it knows. The mind cannot comprehend what it doesn’t know, what it doesn’t think, what is beyond all kinds of knowledge that the mind could learn and remember. Just as the ego (the idea/perception of I) cannot comprehend ‘selflessness’ or ‘I-lessness’. And hence, the yoga practice is all about annihilating the ego and egoism to allow the mind to realize selflessness and see things as they are, transcending all the worldly egoistic thinking and beliefs.
