There's nothing wrong and it's common that most minds are being proud of the attachment and identification towards their particular ancestral, tribal, social, cultural, spiritual or religious thinking, belief, values and practice that influencing their particular way of living, perspective, reasoning power, judgment and expectation towards themselves and everything, where the idea of letting go those existing attachment and identification in the teachings and practice of yoga and buddhism, is something unthinkable or extremely wrong and insane for these minds.
There are many minds are interested in yoga, and might be practicing and teaching yoga under certain names and forms for some time, however, the presence of intense attachment and identification or pride towards their particular thinking, belief, values and practice deriving from as well as empowering ignorance and egoism, that built around survival instinct, separateness, duality, fear, desire and greed, is indeed the biggest hindrance for the minds to advance further in the path of self-inquiry and self-realization.
For the minds that are aware of ignorance and sincerely want to be free from ignorance, to transcend the inevitable suffering of restless and selfless impermanent changes (ceaseless and countless births and deaths within the modification of the mind, of different states arising and passing away being conditioned and limited by cause and effect), not only that a calm and quiet mind is essential, but an open mind without any attachment and identification towards any particular worldly egoistic thinking, belief, values and practice conditioning the mind to analyze, reason, judge and expect towards everything, is what allowing self-inquiry to be happening as it is, intentionlessly and effortlessly.
Need not going everywhere in searching for a Guru other than the mind itself, to enlighten oneself, to answer one's questions, to remove one's doubts, or to heal one's painful suffering, but one only needs to let go the pride, the attachment and identification towards the existing egoistic thinking and belief in the mind, all and everything is already there teaching and guiding this mind onto the path of self-inquiry and self-realization.
Feel annoyed, disgusted, offended, intimidated, threatened and angry by this teaching or anything that is contradicting with the existing thinking and belief, values and practice in the mind, that the mind categorized as wrong, bad, negative and meaningless? That's the precious moment to reflect towards what is going on in this mind, to know Thyself.
The minds that don't know, they fall in love with what 'amazed' them, they miss what 'they fall in love with' upon their absence, they regret if they did something that they think they shouldn't do or didn't do something that they think they should have done. And that's their freedom of thinking, actions and reactions.
The minds that know, they don't fall in love with anything, they don't miss anything, they don't regret anything. Such minds can be kind and accommodating towards all and everyone non-discriminatively and unconditionally.
Letting go the attachment and identification towards the existing thinking, belief, values and practice, is challenging for the minds that have been conditioned deeply by such names and forms, however, it will become effortless, upon the mind realizing the 'intention' or 'motif' that gives rise to the existence of all the different kinds of passionate egoistic thinking, belief, values and practice in the world of human beings. Such liberated minds can still live life in certain way like everyone else, while living and mingling among all kinds of human beings of different thinking, belief, values and practice, however, the minds are free from attachment and identification towards any thinking, belief, values and practice, and thus, be able to respect and accommodating towards all kinds of diversities in the world, free from separateness and discrimination.
The minds that are not free from attachment and identification or pride towards their particular inherited or adopted thinking, belief, values and practice, will always be conditioned by the sense of separateness and discrimination towards some other forms of thinking, belief, values and practice that the minds dislike and disagree with, that are contradicting with their own particular thinking, belief, values and practice.
The realization of selflessness, that leads to non-separateness or oneness beyond all kinds of different qualities of names and forms, is the only way to achieve world peace under many diversities effectively and non-violently.
Inquire towards any forms of teachings or beliefs that propagate and empower the sense of separateness and discrimination, and the sense of pride towards identity and attachment towards such teachings or beliefs and their particular community, while talking highly about promoting peace and harmony in the world ( what they claimed and possessed as their world) based on their own particular thinking, belief, values and practice, while using temptation, rewards, conversion and education, or else, oppression, force, control, disciplinary, threat, punishment, or violence, with the intention or aspiration of 'uniting' and 'unifying' all and everyone under a particular vision based on their community of particular thinking, belief, values and practice, while eliminating or pushing away all the others that don't 'fit' into the vision of their world. Such 'trace' can be found in all kinds of culture, spirituality, religion, political party, organization, association and authorization. Not that these names and forms are bad and wrong. They have their own purposes and functions. It depends on whether they are run by the minds that are under the influence of ignorance and egoism, or free from the influence of ignorance and egoism.
