This volume deals with practical issues of transformation of the human being, which, according to Sri Aurobindo, must emerge from the semi-animal state and become the embodiment of the Divine Truth-Consciousness, or supramental consciousness, on Earth. Such a transformation involves a complete transformation of not only the consciousness and inner state of a person, but, ultimately, his physical body into an immortal divine being. This book presents methods for transforming the mental and vital parts of human nature (constituting the sphere of thinking, emotions and feelings), as a result of which a person can discover limitless abilities and become a conductor of true Knowledge, Power and Bliss in the material world.
