Adhyātma–Adhibhūta–Adhidaivata Correspondences and the Triguṇa Lakṣaṇas (Śānti-parva 301)
रूपेण दृष्टि संयुक्तां प्राणं गन्धगुणेन च | शब्दे सक्तं तथा श्रीत्र॑ जिह्ना रसगुणेषु च
rūpeṇa dṛṣṭi-saṃyuktā prāṇaṃ gandha-guṇena ca | śabde saktaṃ tathā śrotraṃ jihvā rasa-guṇeṣu ca ||
毗湿摩说：眼根与色相相应；生命之息（prāṇa）与香（嗅）之质相连。耳根执著于声，舌根执著于味。诸根本性趋向各自境界；明了此种系属，乃自制与正行之要。

Educational Q&A
Each sense faculty is naturally bound to its corresponding object—sight to form, hearing to sound, tongue to taste, and so on. Recognizing this built-in tendency helps one practice restraint (dama) and avoid being carried away by sense-attachment, which is central to dharmic living.
In Śānti Parva, Bhīṣma instructs Yudhiṣṭhira on dharma and inner discipline. Here he explains how the senses relate to their objects, as part of a broader discussion on controlling desire and cultivating steadiness of mind.
