The Maitrayaniya (Maitrāyaṇīya) or Maitri Upanishad belongs to the Maitri or Maitrayaniya branch of the Kṛṣṇa Yajurveda, though some texts assign it to the Sāmaveda. It figures as number 24 in the Muktika canon of 108 Upanishads under the name of the Maitrāyaṇi Upanishad, which is included there as a Sāmānya Upanishad, associated with the Samaveda. The Dīpikā, a notable commentary on this text was written by Rāmatirtha.
