The embodied soul, having realized the truth about the Self, becomes free from grief and obtains the wished-for goal.
By reflection, reasoning and instructions of teachers, the truth is known. Not by ablutions, not by making donations, nor by performing hundreds of breath control exercises.
What is enquiry into the Truth? It is the firm conviction that the Self is real, and all, other than That, is unreal.
Even after the Truth has been realised, there remains that strong, obstinate impression that one is still an ego - the agent and experiencer. This has to be carefully removed by living in a state of constant identification with the supreme non-dual Self. Full Awakening is the eventual ceasing of all the mental impressions of being an ego.
