[Advaita-l] ya eko avarno...

[Gerald Penn]

Hello,

   Can anyone tell me the provenience of the following prayer?
My apologies for the likely inaccuracy of this transliteration.

Ya eko avarno bahuddha shakti yogaa
Dwarnaananekaan nihitartho dadhaati
vichaiti chaante vishvamaadhau sa devaha
sa no buddhayaa shubhayaa samyunaktu

Yo devaaanaam prabhavaschod bhavascha
vishvaa deepo rudro maharshih
hiranyagarbham pashyati jaayamaanaam
sa no buddhayaa shubhayaa samyunaktu

Thanks,
Gerald
