What are you doing to BE? Where exactly is the question of doing something (for Realization) arising? Is it not in the mind? Is it not to a phantom entity, an object presuming subjectivity, an illusory entity that has no existence whatsoever apart from consciousness? When the nature or identity of the one who raises the question of "what should I do to Realize", is clearly and deeply understood, what is left? Where is the question of doing or undoing anything?
The next question is what about Sadhana (practice) as recommended by so many teachers. The Sadhana ( if properly understood) is not about doing something( including rituals, meditation, etc.), but about Being. Just BE.
