वेदे विश्वासटिप्पन्यः

The kubjikA upaniShad, a text at the smArta-pashchimAmnAya interface, cites the below 5 R^ik-s by pratIka:

sahasrashIrShaM rudraM sahasrAkSham | te pa~ncharchyaH | tasyAH shikhAyA madhye puruShaH kubjeshvaraH sthitaH ||

Here kubjeshvara is navAtman bhairava, the consort of kubjikA

To date, I have not been able to locate these verses in any Vedic text, even though the majority of the kubjikA upaniShad citations are traceable to the two extant atharvaveda saMhitA-s, in line with its explicit affiliation with the atharvan tradition.

One could note that the pratIka and concluding dala are close to comparable verses from the nArAyaNa-valli of the mahAnArAyaNopaniShad, recensions of which are appended to both the AV and the taittirIya shruti of KYV. Does it imply that there was once a rudrian variant of the nArAyaNa-valli in a lost AV tradition or was there such an imitation in the pashchimAmnAya.

If so it would be a reverse case of mimicking of the pa~nchabrahma mantra-s in the vaiShNava tradition.(5)
