"There are two ways of doing Yoga, one by knowledge and one's own efforts, the other by reliance on the Mother. In the last way one has to offer one's mind and heart and all to the Mother for her Force to work on it, call her in all difficulties, have faith and bhakti. At first it takes time, often a long time, for the consciousness to be prepared in this way - and during that time many difficulties can come up, but if one perseveres a time comes when all is ready, the Mother's Force opens the consciousness fully to the Divine, then all that must develop develops within, spiritual experience comes and with it the knowledge and union with the Divine."

Sri Aurobindo (1872-1950)Letter from November 13, 1934in "On Himself", SABCL, volume 26, page 455
