The Philosophy of the Upanishads c6.s3.4

c6.s3.4

² An apparently older list has been preserved in the Atharva-parisiṣṭa 2. 13 (Berliner Handschriften, 2. 88), which reckons only 28 Atharva Upanishads, omitting the texts of the older Vedas, but in other respects, as far as it goes, agrees with the lists of Colebrooke and Nārāyaṇa with a single exception.
