The Brahma-sutras (Vedanta Sutra), attributed to Badarayana, are an aphoristic codification of Upanishadic wisdom composed in antiquity and systematized in the early centuries of the Common Era. Comprising 555 terse sutras in four chapters, it examines the nature of Brahman—the ultimate reality—and the relation of Atman to Brahman. Through rigorous argumentation and refutation of rival views, it treats knowledge (pramanas), illusion (māyā), karma, and the means of liberation (moksha). Its compact form invited monumental commentaries—Śaṅkara, Rāmānuja, Madhva—giving rise to Vedānta’s major schools. Today the Brahma-sutras remain a living bridge between metaphysics and practice, informing contemporary debates on consciousness, spirituality, and ethical living.
