Saṃhāra-krama (The Sequence of Cosmic Dissolution) — Yājñavalkya’s Discourse
वदन्ति कारण चेदं सांख्या: सम्यग् द्विजातय: । विज्ञायेह गतीः सर्वा विरक्तो विषयेषु यः
vadanti kāraṇa cedaṃ sāṅkhyāḥ samyag dvijātayaḥ | vijñāyeha gatīḥ sarvā virakto viṣayeṣu yaḥ ||
毗湿摩说道：“数论派——那些真正通达正理的两次生者——宣称此乃真实的因果原则：在此世间，唯有洞察众生一切流转之途，并对诸境（感官对象）生起离染之人，方能在舍身之后获得解脱（mokṣa）。此理，他们说，昭然可明；除此之外，别无他法能得解脱。故而他们称数论本身即为通向解脱之见。”

Educational Q&A
Liberation is said to follow from clear discernment of the various destinies/courses of beings and from detachment (vairāgya) toward sense-objects; the Sāṅkhyas present this discriminative knowledge and dispassion as the decisive means to mokṣa.
In the Śānti Parva’s instruction section, Bhīṣma is teaching about liberation and philosophical paths; here he reports the Sāṅkhya position that true knowledge and detachment are the essential cause leading to freedom after the body is relinquished.
