Vidyā–Avidyā and the Twenty-Fifth Principle
Sāṃkhya–Yoga Clarification
एवं तस्य प्रवृत्तस्य नित्यमेवानुपश्यत: । रागद्वेषौ विवर्धेते हानित्यत्वमपश्यत:
evaṁ tasya pravṛttasya nityam evānupaśyataḥ | rāga-dveṣau vivardhete hānityatvam apaśyataḥ ||
若人久住于外向之行道,日日凝视诸境,而不觉其无常,则贪爱与憎恶便在心中不断滋长。因忽略迁变,心识遂为好恶所缚,而非由明辨所导。
पराशर उवाच
Continual fixation on objects without insight into their impermanence strengthens rāga (attachment) and dveṣa (aversion). Ethical and spiritual clarity arises from seeing transience; otherwise the mind becomes reactive, driven by likes and dislikes.
Parāśara is explaining a psychological-spiritual mechanism: a person who stays in pravṛtti (worldly engagement) keeps observing desirable and undesirable objects, but because he does not perceive their anityatva (impermanence), his inner tendencies of attachment and aversion increase.
