Samastadharmasu (समस्तधर्मसू, IAST: Samastadharmasu) is a Sanskrit-origin Hindu boy-name meaning “Generator and begetter of all dharmas”. From samasta (complete, entire, all together) + dharma (sacred duty, cosmic order, righteousness) + su (from sū, one who generates, produces, or begets), this epithet hails Vishnu as the primordial source from which every form of dharma — cosmic, social, personal, and eternal — is born and sustained.

Meaning, etymology & significance

The root sū means to generate, to bring forth, to give birth; hence samastadharmasu is 'the one who generates all dharmas in their totality.' Samasta emphasises that no strand of dharma is excluded — whether it is ṛta (cosmic truth), sva-dharma (individual duty), sādhāraṇa-dharma (universal ethics), or mokṣa-dharma (the path of liberation) — all arise from Vishnu as their primordial fountainhead. This name positions Him as not merely the guardian but the very origin of righteousness.

Samastadharmasu is a profound liturgical epithet of Vishnu that is rare as a given name due to its length and the unusual terminal form. As a name it may be abbreviated to Dharmashu or Dharmasoo; full pronunciation is sa-mas-ta-dhar-ma-su, with the final u held lightly.
