Dīkṣā-bhedaḥ (Types of Initiation) — Lalitopākhyāna: Hayagrīva–Agastya Dialogue
यथा निलीयते काले प्रपञ्चो नैव दृश्यते / तथैव मीलयेन्नेत्रे एतद्ध्यानस्य लक्षणम्
yathā nilīyate kāle prapañco naiva dṛśyate / tathaiva mīlayennetre etaddhyānasya lakṣaṇam
As when, in time’s concealment, the manifold world is no longer seen, so too one should close the eyes—this is the mark of dhyāna.
