Vijnana Bhairava Tantra
वर्णस्य सविसर्गस्य विसर्गान्तं चितिं कुरु । निराधारेण चित्तेन स्पृशेद्ब्रह्म सनातनम् ॥ ९१ ॥
When the mind is joined with the visarga, at the end of the visarga it is made supportless. In this way the mind is touched by the eternal Brahma, or the supreme consciousness.
english translation
