Brahma-vidyā: Satya–Tapas and the Enumeration of Tattvas
Arjuna–Vāsudeva framed dialogue
ब्रह्मचारिकमेवाहुराश्रमं प्रथमं पदम् । गार्हस्थ्यं तु द्वितीयं स्याद् वानप्रस्थमत: परम् | ततः परं तु विज्ञेयमध्यात्मं परमं पदम्
brahmacārikam evāhur āśramaṁ prathamaṁ padam | gārhasthyaṁ tu dvitīyaṁ syād vānaprastham ataḥ param || tataḥ paraṁ tu vijñeyam adhyātmaṁ paramaṁ padam |
在诸住期（āśrama）之中，人们称梵行（brahmacarya，学生戒行）为第一阶段；家住（gṛhastha）为第二；其后为林栖（vānaprastha）。超越这些，当知至上之位乃内在的自证之道（adhyātma）——出离（sannyāsa），其中对我（Ātman）的证悟为最要。

Educational Q&A
Human life is structured as progressive āśramas: disciplined learning (brahmacarya), responsible social duty (gārhasthya), gradual withdrawal (vānaprastha), and finally the supreme pursuit—adhyātma, the inward realization of the Self, identified with renunciant life.
Vāyu is instructing the listener by outlining the traditional sequence of life-stages and emphasizing that the culmination of this progression is the highest goal: spiritual realization (adhyātma), associated with renunciation.
