These inspirational essays by Sri Aurobindo form a powerful statement of the true attitude to be taken by a sadhak of the integral Yoga: one of a complete and dynamic surrender to the Mother. They describe the triple movement of aspiration, rejection, and surrender, the conditions for a true faith and sincerity, the irresistible power of the Divine Mother’s grace, the need to reconquer the money-force for the Mother’s work, and the joy of a perfect instrumentality through selfless work, surmounting the demands of the ego. The final piece describes the four great powers and personalities of the Divine Mother.
