Words of wisdom are neither good nor bad. They are just what they are. They have no intention or quality to be useful or useless, to be meaningful or meaningless, or to be enlightening or disturbing.
Words of wisdom can be useful and meaningful and enlightening for those who are aware of ignorance in oneself, but they are useless and meaningless and disturbing for those who are not aware of ignorance in oneself.
All minds that are under the influence of ignorance and egoism are being conditioned or influenced by many different types of thinking and belief that are being imprinted into the mind since the birth of this life existence coming from family and cultural background, religious background, parenting, schooling, social mixing and interaction, social medias, and all kinds of information sources, to live life, to think and feel, to act and react.
Most of the time, we don’t really inquire the truth of everything that were passed down to us from generation to generation, and everything that we come in contact with, and we usually put our ‘trust’ onto ‘reliable’ or ‘respectable’ sources to feed or occupy our minds with many different information and ideas, until we start to doubt about something and then we would question or investigate the truth of it, to find out whether it’s true, or not. But that usually won’t happen until we got into trouble and suffer for the consequences of our own ‘incorrect’ or ‘ignorant’ understanding, thinking, belief, way of living, conduct and behavior.
If people don’t question the truth of everything, everyone just live life, think and feel, act and react as how they were being told or informed or influenced by the elders, parents, caretakers, friends, society, communities, groups, associations, gangs, politicians, religious authorities, school teachers, philosophers, and so on.
In Yoga and Buddhism, one has to question the truth of everything including all the teachings or scriptures of yoga and Buddhism, of what all the teachers said and taught. The real teachers won’t be insulted or disrespected or humiliated when the students neither agree nor disagree with what the teachers or any sources informed them, but they would perform self-practice and self-inquiry to realize the truth of the teachings through self-effort and self-realization.
It’s okay if we don’t know many things. It won’t do any harm if we don’t know everything and we are aware of we are ignorant or don’t know the truth of something. But it would be very harmful to oneself and others, if we blind-believe in and blind-agree with and blindly sharing information and ideas that we don’t know whether they are true, or not.
So as there are many ‘yoga teachers’ teach yoga to other people according to what they have learned and heard from the yoga courses that they have attended, just because the books/scriptures/teaching manuals and their teachers say so. Some people don’t mind if the teachings are true, or not, as long as they have some ideas of yoga poses practice sequences with some technical information and interesting spiritual stories to teach in the yoga classes to satisfy the people’s enthusiasm and intention of joining the yoga classes, and earn a living. And there’s nothing wrong with that and it’s everyone’s freedom. One is willingly to present something that one doesn’t really know what does it really means, while others are willingly to follow something that they don’t know where it would lead them to.
The wise never aspire or intent to make other beings to see what they see, or to know what they know. The teachings are everywhere for everyone to take it (practice and realize), or leave it.
Be free and be happy.
