Neither by the practice of yoga nor philosophy, nor by good works nor by learning, does liberation come, but only through the realization that Atman and Brahman are one in no other way.

Sankara says:- Neither by the practice of yoga nor philosophy, nor by good works nor by learning, does liberation come, but only through the realization that Atman and Brahman are one in no other way.(1) VivekaChudamani v 56, pg 25

Sri, Sankara goes on to say:- A sickness of not cured by saying the word “medicine.” You must take the medicine. Liberation does not come by merely saying the word “Brahman.” Brahman must be experienced. Until you allow this apparent universe to dissolve from your consciousness, until you have experienced Brahman, how can you find liberation just by saying the word Brahman? The result is merely a noise. Until a man has destroyed his enemies and taken possession of the splendour and wealth of the kingdom, he cannot become a king by simply saying “I am a king.”

A buried treasure is not uncovered by merely uttering the words: “Come forth.” You must follow the right directions, dig, remove the stones and earth from above it, and then make it your own. In the same way, the pure truth of the Atman, which is buried under Maya and the effects of Maya, can be reached by meditation, contemplation, and other spiritual disciplines but never by subtle arguments.

What is the use of doing meditation on the base of waking entity, which is false self within the false experience? Meditation is not the means to Self –Knowledge or Brahma Gnana or Atma Gnana. Meditation is not the goal itself because it practiced on the base false self within the false experience.

Wisdom dawns only when ignorance vanishes. Ignorance vanishes only when the waking entity (ego) becomes aware of the fact that, it itself is not the self. Thus by practicing meditation on the false self within the false experience is like try to catch fish in desert sand. --FORMLESS PATH
