Dīkṣā-bhedaḥ (Types of Initiation) — Lalitopākhyāna: Hayagrīva–Agastya Dialogue
शिष्यमाहूय रहसि वाससा बद्धलोचनम् / कारयित्वा प्रणामानां साष्टाङ्गानां त्रयं गुरुः
śiṣyamāhūya rahasi vāsasā baddhalocanam / kārayitvā praṇāmānāṃ sāṣṭāṅgānāṃ trayaṃ guruḥ
The guru summons the disciple in secrecy and binds his eyes with a cloth; then he has him perform three sāṣṭāṅga praṇāmas—full prostrations of eight limbs.
