The purest doctrines, such as those of Ramana Maharshi, Padma Sambhava, Huang Po and Shen Hui, just teach that it is sufficient by analysis to comprehend that there is no entity which could have effective volition, that an apparent act of volition when in accord with the inevitable can only be a vain gesture and, when in discord, the fluttering of a caged bird against the bars of his cage. When he knows that, then at last he has peace and is glad.
