[Advaita-l] antahkarana vrutti verse request

[aham brahmaasmi]

नमो विद्वद्भ्य: !

There is a verse about the antahkarana vritti that changes from vishayakara
-vrutti to  the akahandaara vrutti and then itself falls off, akin to the
twig that lights the funeral pyre and then itself burns off.
'स्वयमेवोपशाम्यति'

If my above understanding is okay, please would you point me to the
references?

thank you in advance,
Sakshi
