Brahma-vidyā: Satya–Tapas and the Enumeration of Tattvas
Arjuna–Vāsudeva framed dialogue
तस्योपायं प्रवक्ष्यामि पुरस्तात् तं निबोधत । फलमूलानिलभुजां मुनीनां वसतां वने
tasyopāyaṁ pravakṣyāmi purastāt taṁ nibodhata | phalamūlānilabhujāṁ munīnāṁ vasatāṁ vane ||
ວາຍຸກ່າວວ່າ: «ບັດນີ້ຂ້າພະເຈົ້າຈະກ່າວລ່ວງໜ້າເຖິງວິທີບັນລຸຄວາມຮູ້ນັ້ນ; ຈົ່ງເຂົ້າໃຈດ້ວຍຄວາມໃສ່ໃຈ. ສໍາລັບພະມຸນີຜູ້ຢູ່ໃນປ່າ ດໍາລົງຊີວິດດັ່ງນັກບວດ—ອາໄສຜົນໄມ້ ແລະ ຮາກໄມ້ ແມ່ນກະທັ້ງລົມເປັນອາຫານ—ນີ້ແມ່ນວິໄນທີ່ຄ້ຳຈຸນທຳຂອງຜູ້ຢູ່ປ່າ (ວານະປຣັສຖະ)».
वायुदेव उवाच
Vāyu teaches that a practical ‘means’ toward self-knowledge is disciplined living aligned with āśrama-dharma—especially the forest-dweller’s path marked by simplicity, restraint, and ascetic subsistence (fruits, roots, and even air), emphasizing detachment and tapas as supports for inner realization.
Vāyudeva speaks to his listeners and announces that he will explain the method for attaining the intended goal (implied: self-knowledge). He then points to the forest-sage model of life—dwelling in the woods and living on minimal sustenance—as an exemplar of the vānaprastha/ascetic discipline.
