Dīkṣā-bhedaḥ (Types of Initiation) — Lalitopākhyāna: Hayagrīva–Agastya Dialogue
अद्वैतं भाव येन्नित्यं नाद्वैतं गुरुणा सह / न निन्देदन्यसमयान्वेदशास्त्रागमादिकान्
advaitaṃ bhāva yennityaṃ nādvaitaṃ guruṇā saha / na nindedanyasamayānvedaśāstrāgamādikān
Let one ever abide in the contemplation of Advaita; yet one should not assume “non-duality” in one’s conduct toward the Guru. Nor should one revile other paths, or the Vedas, Śāstras, Āgamas, and the like.
