In this book, Sri Aurobindo, an Indian philosopher and poet, succinctly and clearly explains what is the secret of the Divine Power of the Mother, whose mercy is allowed by the Almighty, as well as how the majestic Power manifests itself at different levels of Existence and what is the essence of interaction with it. The deeper the manifestation of faith, sincerity and devotion of a person, the greater the mercy and stronger the protection of the Mother, the living Divine Presence. The Sacred Power favors only those who reject lies, ignorance and selfishness, but strive for absolute openness and true selflessness.
