Sri Aurobindo explains the fundamental principles and practices of his system of Yoga. The philosophical and psychological foundations of his spiritual teaching are taken up in the first quarter of the book. The remaining portion deals with his method of spiritual practice.
Sri Aurobindo’s teaching states that this One Being and Consciousness is involved here in Matter. Evolution is the method by which it liberates itself; consciousness appears in what seems to be inconscient, and once having appeared is self-impelled to grow higher and higher and at the same time to enlarge and develop towards a
greater and greater perfection. Life is the first step of this release of consciousness; mind is the second; but the evolution does not finish with mind, it awaits a release into something greater, a consciousness which is spiritual and supramental. The next step of the evolution must be to wards the development of Supermind and Spirit as the dominant power in the conscious being. For only then will the involved Divinity in things release itself en
tirely and it become possible for life to manifest perfection.
