The word Sat is used for truth, reality, and goodness — and for all praiseworthy action. The traditions explore this rich term that unites ontology and ethics. Shankara teaches that Sat is the nature of Brahman — pure being, pure reality. Ramanuja sees it as affirming that the Lord is the ground of all truth and goodness. Madhva identifies Sat with the Lord's eternal, independent reality. Abhinavagupta interprets Sat as the affirmation that existence itself is Shiva-consciousness — truth and goodness are the nature of reality, not human inventions. Vallabha teaches that every auspicious action reflects Sat — the Lord's nature — and acknowledging this connects all goodness to its divine source. The bhakti tradition sees Sat as the devotee's affirmation that the Lord is real, true, and good. Tilak interprets Sat as both ontological and ethical — to act in truth is to act rightly, grounding the karma-yogi's action in reality. Vivekananda teaches that Sat means both reality and goodness, which are one in the Vedantic view — living in truth means living in alignment with the fundamental nature of existence. This profound verse collapses the distinction between what is real and what is good.
