Sanatana Dharma - Aka Hinduism (1st Bin)

[Bodhi]

Ashok Ji,

credit for the find is to google.

mahopaniShad is in the 108 list, and some are pointing that it is in the sAmaveda, some other sources say it is in atharvaveda. I have not verified yet.

some relevant references:

Dear Bhagavatas,
                I request someone to please clarify if Mahopanishad,
Narayana Upanishad and Mahanarayaniya Upanishad refer to three
independent upanishads or if some of the aforementioned are merely
multiple names for the same body of text. If these are distinct,
please indicate which of the four vedas to which each belongs. Thank
you.

adiyEn rAmAnuja dAsan,

<!--QuoteBegin-->QUOTE<!--QuoteEBegin-->[ They are different texts. <b>Mahopanishad and the Mahanarayana are  quoted by Ramanuja</b>, and the Narayana Upanishad is not. The Mahanarayana
  Upnishad is also called the Yajniki Upanishad and properly placed
  is the concluding part of the Taittiriya Upanishad, and hence belongs
  to the Krishna Yajur Veda.  The Narayana Upanishad belongs to the

So, this will place it pre-rAmAnuja at the least.

Even the bhAsya-s upon sri rAmanuja refer explicitly to mahopanishad:

Yann-moola-kAraNam aBhudhyatha srushti vaakyai:
BrahmEthi vaa sadhithi vaa aathmagirA aTavaa tath
NaarAyaNasthvithi mahOpanishadh Braveethi
souBAlikee PrabrutaYOapi anujagmu: yEnAm

(Meaning) :MahOpanishad dealing with the creation of the universe
states that the ancient kaaraNam (reason) for Srushti  is described by
the  Vedic word , Sath or Brahman or Aathmaa . That aadhi kaaraNam
for the creation of this naama-roopa prapancham has been identified
further as none other than  Sriman NaarAyaNan .  SubhAlOpanishad
and other upanishads follow the path laid out by MahOpanishad .
