The Ishavasya Upanishad (or simply Isha) is one of the shortest of its kind, and basically represents a brief philosophical poem discussing the soul/self (Atman). This edition contains the Kanva recension, consisting of 18 verses.

The words “Ishavasyam” literally translates to “enveloped by the Lord” and refers to the theory of soul (Atman); a concept used in both dualism and non-dualism.
