Samadhi

Samadhi (समाधि samādhi, ) is the state of consciousness induced by complete meditation. The term's etymology involves "sam" (together or integrated), "ā" (towards), and "dhā" (to get, to hold). Thus the result might be seen to be "to acquire integration or wholeness, or truth" (samāpatti). Another possible etymological analysis of "samādhi" is "samā" (even) and "dhi" (intellect), a state of total equilibrium ("samā") of a detached intellect ("dhi").

Rhys Davis holds that the first attested usage of the term samādhi in Sanskrit literature was in the Maitri Upanishad.
