Dīkṣā-bhedaḥ (Types of Initiation) — Lalitopākhyāna: Hayagrīva–Agastya Dialogue
अद्यप्रभृति मे पुत्रान्रक्ष मां शारणागतम् / इत्युक्त्वा गुरुपादाव्जे शिष्यो मूर्ध्नि विधारयेत्
adyaprabhṛti me putrānrakṣa māṃ śāraṇāgatam / ityuktvā gurupādāvje śiṣyo mūrdhni vidhārayet
From this day forth, protect me and my sons; I have come seeking refuge. Having said so, the disciple should place upon his head the lotus-feet of the Guru.
