The personality (vyakti) is but a product of imagination. The self (vyakta) is the victim of this imagination. It is the taking yourself to be what you are not that binds you. The person cannot be said to exist on its own rights; it is th...e self that believes there is a person and is conscious of being it. Beyond the self (vyakta) lies the unmanifested (avyakta), the causeless cause of everything.
When your personality dissolves only the witness remains. Then you go beyond the witness. Do not ask how it happens. Just search within yourself
