In the interval between the knowledge of the identity and annihilation of vasanas, there will be illusion.

Devotee:  Does not illusion become inoperative even before identity with Brahman results (Brahmakaravritti)? Or does it persist even afterwards?

Ramana Maharishi:  Illusion will not persist after vasanas are annihilated. In the interval between the knowledge of the identity and annihilation of vasanas, there will be illusion.
