Brahma-vidyā: Satya–Tapas and the Enumeration of Tattvas
Arjuna–Vāsudeva framed dialogue
अतत्तत्त्वानि वक्ष्यामि याथातथ्येन हेतुना । विषयस्थानि सर्वाणि वर्तमानानि भागश:,अब मैं यथार्थ युक्तिके द्वारा पदार्थोमें विभागपूर्वक रहनेवाले सम्पूर्ण तत्त्वोंका वर्णन करता हूँ
atattattvāni vakṣyāmi yāthātathyena hetunā | viṣayasthāni sarvāṇi vartamānāni bhāgaśaḥ ||
Vāyu bersabda: “Kini akan kujelaskan prinsip-prinsip itu sebagaimana adanya, ditopang oleh nalar yang kukuh—seraya memperlihatkan bagaimana segala unsur yang bekerja dalam ranah pengalaman hadir dalam pembagian-pembagian yang berbeda.”
वायुदेव उवाच
Educational Q&A
That true understanding should be presented “as it is” (yāthātathya), grounded in reason (hetu), by distinguishing the operative principles (tattvas) that structure experience into clear categories (bhāgaśaḥ).
Vāyu-deva begins a didactic exposition: he announces that he will systematically describe the fundamental principles that function within the domains of experience, setting up a structured philosophical explanation.
