The truth seeker's goal is to acquire non dual wisdom, whereas the yogis goal is to attain Samadhi

The goal of the seeker after truth is not the same of the yogi. The truth seeker's  goal is to acquire non dual wisdom, whereas the yogis goal is to attain Samadhi. This non dual wisdom is to know all the three states are erupted out of the soul, which is in the form of Consciousness sustained by Consciousness finally they, dissolve as Consciousness.

All the three states are an object to the 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 space, time and form. 

By Gazing at nose-tip one cannot acquire non dual wisdom because a man is false entity within the false experience. When the self is not the form but the self is formless then what is the use of doing practice on the base of the form, which is the false entity. Pursuit of truth is to know what truth is and what is false and realize and establish in the truth.  If one wants wisdom then he must look on everything as consciousness.  He must have firm conviction that, —everything is Consciousness. 

All the three states disappear back to the soul.  All the three states are mere mirage created out of consciousness. All the names and forms are part of the mirage. The mirage appears as waking or dream (duality) and disappears as deep sleep (non-duality) thus the universe, appears as Mind. And mind appears as waking or dream. Thus mind is also Consciousness because it is created out of 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 his- self 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.
