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 ||
Vāyu disse: “Agora declararei de antemão o meio para alcançar isso (o conhecimento do Si); compreendei-o com atenção. Para os sábios que habitam na floresta, vivendo à maneira de ascetas—sustentados por frutos e raízes, e até pelo ar como alimento—esta é a disciplina que mantém o dharma do vānaprastha, o morador da floresta.”
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.
