Vānaprastha-vṛtti and the Transition toward the Fourth Āśrama (वानप्रस्थवृत्तिः चतुर्थाश्रमोपक्रमश्च)
तत्राव्यक्तमयीं विद्यां शृणु त्वं विस्तरेण मे । तथा व्यक्तमयं चैव सांख्ये पूर्व निबोध मे,वत्स! तुम सांख्यदर्शनमें वर्णित अव्यक्तविद्याका विस्तारपूर्वक मुझसे श्रवण करो। सर्वप्रथम सांख्यशास्त्रमें कथित व्यक्तविद्याको मुझसे समझो
tatrāvyaktamayīṃ vidyāṃ śṛṇu tvaṃ vistareṇa me | tathā vyaktamayaṃ caiva sāṅkhye pūrvaṃ nibodha me, vatsa ||
Vyāsa nói: “Nay con hãy nghe ta giảng tường tận về tri kiến liên hệ đến ‘Vô hiển’ (Unmanifest). Và trước hết, hỡi đứa con yêu dấu, con hãy hiểu từ ta tri kiến về ‘Hiển’ (Manifest) như được dạy trong Sāṅkhya.”
व्यास उवाच
Vyāsa frames a structured Sāṅkhya-style instruction: first comprehend the principles of the Manifest (vyakta)—the knowable, differentiated domain—then proceed to the Unmanifest (avyakta), the subtler metaphysical ground. The ethical thrust is disciplined inquiry: clear understanding of the visible order prepares the mind for insight into the transcendent.
In the didactic setting of Śānti Parva, Vyāsa addresses a disciple affectionately (“vatsa”) and announces the next section of teaching. He signals a methodical exposition—beginning with the manifest categories taught in Sāṅkhya and then moving to the unmanifest doctrine—indicating a transition into deeper philosophical analysis.
