Knowledge of the self is the mother of all knowledge. So it is incumbent on me to know my self, to know it completely, to know its minutiae, its characteristics, its subtleties, and its very atoms. Kahlil Gibran
Just as the fire is the direct cause for cooking, so without Knowledge no emancipation can be had. Compared with all other forms of discipline Knowledge of the Self is the one direct means for liberation. Adi Shankara
