Isha Upanishad
The Isha Upanishad (Sanskrit: ईशोपनिषद्, IAST: Īśopaniṣad), also known as Shri Ishopanishad, Ishavasya Upanishad, or Vajasaneyi Samhita Upanishad, is one of the shortest Upanishads, embedded as the final chapter (adhyāya) of the Shukla Yajurveda. It is a Mukhya (primary, principal) Upanishad, and is known in two recensions, called Kanva (VSK) and Madhyandina (VSM).
