One should inquire into the nature of the universe first, then into the individual and finally, into the highest, the soul or Atman. Seeker should not go on wasting his time in imagining things. He should search for truth which means he must examine what is before him
Yoga and religion omits this important preliminary inquiry into the world and hence never reaches truth. This does not mean the world should disappear in Samadhi but that its true nature should be determined. If the yogis really got emancipation in Samadhi, then ordinary men would also get it in deep sleep!
Therefore we must always be engaged in an inquiry into the nature of this universe or mind, the individual personal self (ego) and Atman (soul). When the notions of reality of the world and ego are destroyed, what remains is pure consciousness. The destruction of the world and ego does not mean that they should become imperceptible to the senses, but there should arise a determination of their unreal nature: for if that were not the case people may find emancipation without efforts on their part as during dreamless sleep, and fainting (when percepts altogether disappear).
"If a person cannot undertake the study into the nature of the self, either through a dull intellect or through want of accessories for such inquiry, he must be constantly engaged in the meditation on true self, which is in the form of consciousness." The term accessories here mean "Reason which is based on the formless self.
"The Yogi who moves unseeing through this world is not better than a lump of clay in human form; it is not imperceptions of the world that is needed but the intellectual realization that its substratum is idea.
