Ananda Sutram is the magnum opus of Shrii Shrii Anandamurti, composed in 1961. In just 85 sutras (aphorisms) across five chapters, it presents a complete philosophical system covering epistemology, metaphysics, ethics, and spiritual practice. Each sutra is a compressed gem of meaning, expanded upon in the author's commentary. This text serves as the philosophical backbone of the entire Ananda Marga tradition.
