"Sadhana - The Realisation of Life" is a collection of spiritual discourses given by Rabindranath Tagore. A repository of the timeless wisdom of the East, Sadhana is one of the most profound books on spirituality. Compiled and translated by Tagore from his Bengali lectures, the book consists of eight essays, in which Tagore answers some of the most profound questions of life: Why did God create this world? Why would a Perfect Being, instead of remaining eternally concentrated in Himself, go through the trouble of manifesting the Universe? Why does evil exist? Do love and beauty have a purpose? Tagore masterfully brings the spiritual truths behind these profound questions to light, with his lucid explanations of the Sanskrit verses of the Upanishads (Indian spiritual texts dating to 800 B.C.) and the eternal teachings of Lord Jesus and Buddha.
