The volume presents the narrative of his personality until his twenty-fourth year and the training he underwent at the feet of his Master for the attainment of spiritual insight and realisation. It takes into account the theme around which the Swami's life is drawn —the theme of Hinduism, its setting, its basis and its structure. It reveals the growth of a gigantic mind through modern agnosticism into complete saintship. It presents the character of the Swami's Master in the light in which the Swami himself understood him.
The present volume deals with the narrative of the Swami's life as the wandering monk, and later on as the bearer of the message of Hinduism to the West. It takes the reader through the scenes of the Swami's life of intense austerities and Sadhanas in the Barana-gore Math, of his travels and silent preaching throughout the length and breadth of Hindusthan, prior to his departure for America, and of his triumphant public career as the apostle of Vedantism during his sojourn in the West.
The volume speaks of the Swami's attempts at re-modelling the Indian thought-world, of his restating the entire contents of the Sanatana Dharma and the ancient Aryan culture, and of his bringing about a religious revival in India.
