Dear list members,

Can any of the list members give me the textual source  for where the bhūsūktam comes from?

I've seen an internet  reference to mahānārāyaṇopaniṣad (28) but I haven't been able to find the bhūsūktam in the mahānārāyaṇopaniṣad.

The first few verses are from the Taittiriya Samhita 1.5.3 but I'm looking from where the bhūsūktam as a whole occurs because  I'm looking for the scriptural source of the Gayatri mantra:

dhanurdharāyai vidmahe

sarvasiddhyai ca dhīmahi

tanno dharā pracodayāt

 

which is part of the  bhūsūktam .

I've searched the on-line resources (Bloomfields Concordance, GRETIL and Muktabodha) and haven't found it.

Thanks,

Harry Spier
