Kalasattama (कालसत्तम, IAST: Kālasattama) is a Sanskrit-origin Hindu boy-name meaning “The greatest and most real among all time”. From kāla (time) + sat (being, real, good) + tama (superlative suffix — most), Kālasattama proclaims Viṣṇu as the highest reality within and beyond all temporal existence.

Meaning, etymology & significance

Kāla in Sanskrit encompasses both time as a cosmic force and death as its most visible expression; sat denotes existence, truth, and goodness simultaneously. The superlative suffix -tama elevates this to the ultimate degree: Viṣṇu is the most truly existent among all that time contains, the sat that does not perish when kāla sweeps all else away. This name carries a profound Vedāntic resonance, pointing to the Lord as the immortal ground of a transient cosmos.

Viṣṇu is invoked as Kālasattama in the Sahasranāma to honour His transcendence of the very time-flow that governs all creation. Pronounced kaa-la-SAT-ta-ma; as a long compound it is more suited to devotional recitation than to everyday use as a given name.
