Brahma-vidyā: Satya–Tapas and the Enumeration of Tattvas
Arjuna–Vāsudeva framed dialogue
इस प्रकार श्रीमह्याभारत आश्वमेधिकपर्वके अन्तर्गत अनुगीतापर्वमें ब्राह्मणगीताविषयक चौंतीसवाँ अध्याय पूरा हुआ,ब्रह्म सत्यं तप: सत्यं सत्यं चैव प्रजापति: । सत्याद् भूतानि जातानि सत्यं भूतमयं जगत् ब्रह्म सत्य है, तप सत्य है और प्रजापति भी सत्य है। सत्यसे ही सम्पूर्ण भूतोंका जन्म हुआ है। यह भौतिक जगत् सत्यरूप ही है
brahma satyaṃ tapaḥ satyaṃ satyaṃ caiva prajāpatiḥ | satyād bhūtāni jātāni satyaṃ bhūtamayaṃ jagat ||
Arjuna said: “Brahman is truth; austerity is truth; and Prajāpati too is truth. From truth all beings are born, and this world—made up of beings—is itself of the nature of truth.”
अजुन उवाच
The verse identifies truth (satya) as the foundation of ultimate reality (Brahman), spiritual discipline (tapas), and the creative principle (Prajāpati), asserting that all beings arise from truth and that the world is grounded in that reality.
Within the Anugītā section of the Aśvamedhika Parva, Arjuna voices a doctrinal summary emphasizing satya as the source and substance of creation, aligning ethical truthfulness with metaphysical reality.
