Dīkṣā-bhedaḥ (Types of Initiation) — Lalitopākhyāna: Hayagrīva–Agastya Dialogue
उत्तमा तत्त्वचिन्ता स्याज्जपचिन्ता तु मध्यमा / अधमा शास्त्रचिन्ता स्याल्लोकचिन्ताधमाधमा
uttamā tattvacintā syājjapacintā tu madhyamā / adhamā śāstracintā syāllokacintādhamādhamā
Supreme is contemplation upon tattva (the true principle); middling is contemplation upon japa (sacred repetition); inferior is preoccupation with śāstra alone; and lowest of the low is anxiety over worldly matters.
