Vijnana Bbhirava Tantra

णवािदसमु ारात ् तु ा े शू भावानात ।्
शू या परया शा शू तामिे त भरै िव ॥ ३९ ॥

O Bhairavi, one who repeats the Pranava (Aum) perfectly,
while concentrating on the void for protracted periods,
experiences the void, and by that void the transcendental
shakti (is revealed).


िवमते हादिे व शू भतू ं िविचयते ।्
तवै च मनो लीन ं ततयभाजनम ॥् ५८ ॥

O great Goddess, one should concentrate on this universe
as nothing but void. Dissolving the mind also like this, one
then experiences the state of laya, or total dissolution.
