अव्यक्त–व्यक्त–कारणकार्यविवेकः
Avyakta–Vyakta and Causality: Discrimination of Field and Knower
उद्यन् हि सविता यद्वत्सृजते रश्मिमण्डलम् | स एवास्तमपागच्छंस्तदेवात्मनि यच्छति
udyan hi savitā yadvat sṛjate raśmimaṇḍalam | sa evāstam apāgacchaṃs tadevātmany yacchati ||
毗湿摩说：“譬如太阳升起时，将其光轮之芒射向四方；落下时，又把那些光芒收摄归于自身。同样，具身之我入于身时，借诸根如光线般的作用向外伸展，以取五境；离身之际，便将诸作用收回内里，并一并携去。”
भीष्म उवाच
Educational Q&A
The verse teaches that sense-activity is an outward extension of the embodied self, and that mastery lies in the ability to withdraw and gather the senses back within—like the sun retracting its rays—especially at the time of departure from the body.
In the Śānti Parva instruction, Bhīṣma explains to the listener a philosophical analogy: the sun’s daily emission and withdrawal of rays illustrates how the jīva engages the world through the senses and later retracts those faculties when leaving the body.
