Sāṅkhya Yoga · Verse 14
"मात्रास्पर्शास्तु कौन्तेय शीतोष्णसुखदुःखदाः | आगमापायिनोऽनित्यास्तांस्तितिक्षस्व भारत"
"mātrā-sparśās tu kaunteya śītoṣṇa-sukha-duḥkha-dāḥ | āgamāpāyino 'nityās tāṃs titikṣasva bhārata"
The contacts of the senses with their objects, oh son of Kuntī, produce cold and heat, pleasure and pain. They come and go, are impermanent; endure them, oh Bhārata
The teaching becomes practical: mātrā-sparśāḥ (contacts of senses with objects) are the interface where we experience the world. Their fruits are opposite pairs: śīta-uṣṇa (cold-heat), sukha-duḥkha (pleasure-pain).
Āgama-apāyinaḥ (coming and going) — everything sensory is temporal. Anityāḥ (not-eternal, impermanent) — they do not deserve extreme attachment or aversion.
The imperative titikṣasva (endure, tolerate) is the practice of yoga. Not elimination of sensation but capacity to endure without reaction. Bhārata (descendant of Bharata) recalls the nobility of lineage.
