If one feels he is doer one must reap the fruit of his action. if one inquires ‘who is the doer?’ and enters the heart, the doership idea will end and triple karma is destroyed. this is indeed is liberation.—Maharishi Ramana.
Maharishi Ramana was such a saint who used his own experience of self-realization without reading scriptures. his words come from Samadhi. when we think that we are the doer of any Karma we have to reap the fruit of that karma. as you know the method of Maharishi was self-inquiry. so when we will put the question to ourself ‘ who is the doer? and our mind will go back and will merge in the self then we can feel the dawn of liberation.
