ONE day it was suggested to Sri Maharshi that no spiritual progress could ever be made without sadhana, or discipline. After a pause he made these observations: "Mind it is that binds man, and the same mind it is that liberates him. Mind is constituted of sankalpa and vikalpa desire and disposition. Desire is of two kinds the noble and the base. The base desires are lust and greed. Noble desire is directed towards enlightenment and emancipation. Base desire contaminates and clouds the understanding. Sadhana is easy for the aspirant who is endowed with noble desires. Calmness is the criterion of spiritual progress. Plunge the purified mind into the Heart. Then the work is over. This is the essence of all spiritual discipline!"
