Willpower should be understood to be the strength of the mind, which makes it capable of meeting success or failure with equanimity. It is not synonymous with certain success. Why should one's attempts always be attended by success? Success breeds arrogance and man's spiritual progress is thus arrested. Failure, on the other hand, is beneficial, inasmuch as it opens his eyes to his limitations and prepares him to surrender himself. Self surrender is synonymous with eternal happiness.
Ramana MaharshiIn truth, you are spirit. The body has been projected by the mind, which itself originates from Spirit.
Ramana MaharshiThere is no mind to control if you realise the self. The mind having vanished, the self shines forth. In the realised man, the mind may be active or inactive, the self remains for him.
