The Gnani cannot change anyone; but he can direct and guide them.

The goal of the seeker after truth is not the same of the yogi. The seekers goal is to acquire Self-Knowledge or Brahma Gnana or Atma Gnana, where as the yogis goal is to attain Samadhi. This non dual wisdom is to know all the three states are erupted out of Consciousness sustained by Consciousness finally they dissolve as Consciousness.

All the three states are seen to Consciousness which is the witness of the three states.  When one has no idea of being separated from the three states, then there is no idea of form, time and space. 

By Gazing at nose-tip one cannot acquire non dual wisdom. But if one want knowledge he must look on everything as soul, have only one thought—everything is consciousness, which is the innermost self. 

All the three states disappear back to the soul. They are only names and forms. Where have they gone? The Mind is also Consciousness. If one knows whole world is dream, or is mental, when all the states go, it becomes Consciousness/soul. Hence he who becomes a sage is able to know himself as Consciousness. This is the meaning of non-causality. Mind seemed to be the cause of duality, but its elimination shows clearly that they are non-different from it.

The Gnani cannot change anyone; but he can direct and guide them.
