[Advaita-l] The other idea of sphuraNa

[Raghav Kumar Dwivedula]

Namaste
I have a request. Is there any traditional textual reference to the idea of
sphuraNa or a reference similar to "अहमहमिति सदा अन्तः स्फुरति".


I was looking for any older reference other than the shloka of Sri Ramana
Maharshi " हृदय-कुहर-मध्ये" etc.

Thank you
Om
