Krishna defines Brahman as the Supreme Imperishable, Adhyatma as one's own nature, and Karma as the creative impulse behind existence. These foundational definitions establish the framework for all that follows. Shankara sees Brahman as pure, attributeless consciousness. Ramanuja sees it as the Supreme Person with infinite attributes. The bhakti tradition finds in these definitions the map for the devotee's journey. Madhva identifies Brahman as Vishnu in His highest aspect, the soul as real and distinct. Abhinavagupta sees the triad as consciousness, its self-reflective power, and its creative dynamism. Vallabhacharya teaches that Brahman is Krishna's highest nature and karma flows as spontaneous expression. Tilak finds in karma as 'creative impulse' a profound validation of action. Vivekananda reads these as providing a complete, empowering worldview where actions matter and nature is rooted in the eternal.
