Vijnana Bhairava 38 Merging with Inner Sound

Tirumanghai Azhvar

The practice of merging in inner sound, the subtle resonance you hear when you close your ears :

anāhate pātrakarṇe 'bhagnaśabde sariddrute |
śabdabrahmaṇi niṣṇātaḥ param brahmādhigacchati || 38 ||

"One shall go to the transcendant Absolute
if one merges/ becomes familiar with
the (immanent) Absolute as sound,
flowing speedily (and) uninterruptedly
inside the ear, spontaneously."
