Absolute honesty is essential in one's search for God (Truth). The subtleties of the Path are finer than a hair. The least hypocrisy becomes a wave that washes one off the Path.
It is your false self that keeps you away from your true Self by every trick it knows. In the guise of honesty this self even deceives itself. For instance your self claims, I love Baba. The fact is, if you really loved Baba you would not be your false self making the self-asserting statement!
