Sadashiva (सदाशिव, IAST: Sadāśiva) is a Sanskrit-origin Hindu boy-name meaning “Eternally auspicious, ever the benevolent one”. Uniting sadā (always) with Śiva (the auspicious, the benevolent), this name — though closely associated with Śaiva theology — appears in the Viṣṇu Sahasranāma to affirm the non-dual teaching that the supreme auspiciousness is one and undivided.

Meaning, etymology & significance

In Śaiva Siddhānta, Sadāśiva is the highest of five manifestations of Śiva, representing pure, untainted grace. Its presence in the Viṣṇu Sahasranāma reflects the Vedāntic vision of Hari-Hara unity, where the attributes of ultimate goodness belong equally to the Supreme. The name reminds the devotee that genuine auspiciousness is not ritual but the very nature of the absolute.

Sadāśiva is one of the most widely recognized sacred names in Hindu tradition, used across Vaiṣṇava and Śaiva communities and found in monastic names throughout India. Pronounced sa-dā-śi-va, with the retroflex śi softly aspirated.
