Daśa-lakṣaṇam
नक्षत्रकल्प: शान्तिश्च कश्यपाङ्गिरसादय: । एते आथर्वणाचार्या: शृणु पौराणिकान् मुने ॥ ४ ॥
nakṣatrakalpaḥ śāntiś ca kaśyapāṅgirasādayaḥ ete ātharvaṇācāryāḥ śṛṇu paurāṇikān mune
നക്ഷത്രകല്പം, ശാന്തികല്പം, കശ്യപൻ, ആംഗിരസൻ മുതലായവരും അതർവവേദാചാര്യന്മാരായിരുന്നു. ഇനി, ഹേ മുനേ, പുരാണസാഹിത്യത്തിലെ പ്രാമാണികരെ ഞാൻ പറയുന്നതു കേൾക്കുക.
The verse lists Nakṣatrakalpa, Śānti, and Kaśyapa, Aṅgiras and others as teachers in the Atharva Veda tradition.
He is outlining the traditional lineages of Vedic and Purāṇic transmission to show how sacred knowledge is preserved and handed down through recognized authorities.
Seek learning from authentic sources and established teacher-student lineages, rather than relying on speculation, since the Bhāgavatam emphasizes received wisdom (paramparā).
