So Ham

Soham (सो ऽहम् so 'ham) is a Hindu mantra, meaning "I am He/That" in Sanskrit.

In Vedic philosophy it means identifying oneself with the universe or ultimate reality.

The mantra is also inverted from so 'ham (the sandhi of saḥ + aham) to ham + sa. The combination of so 'haṃ haṃsaḥ has also been interpreted as "I myself am the Swan", where the swan symbolizes the Atman.

An etymology of haṃsa "swan, goose" as from ahaṃ sa "I am that" is found in the 14th century commentary on the Vedas by Sayana (14th century).

The term so'ham is related to sa, and the phrase translates to "I that very person", according to Monier-Williams. Interpreted as a nominal sentence, it can also be read as "I am he" or "It/He is I". The term is found in Vedic literature, and is a phrase that identifies "oneself with the universe or ultimate reality".

This phrase is found in Principal Upanishads such as the Isha Upanishad (verse 16), which ends:
