Bhagavad Gita 2.14

मात्रास्पर्शास्तु कौन्तेय शीतोष्णसुखदुःखदाः।आगमापायिनोऽनित्यास्तांस्तितिक्षस्व भारत॥

mātrāsparśāstu kaunteya śītoṣṇasukhaduḥkhadāḥ |āgamāpāyino'nityāstāṃstitikṣasva bhārata ||

The contact of the senses with the objects, O son of Kunti, which causes heat and cold, pleasure and pain, has a beginning and an end; they are impermanent; endure them bravely, O Arjuna.

Those external relations that bring cold and heat, pain and happiness come and go; they are not permanent. Endure them bravely, O Prince!

Our plain-language meaning of this verse is waiting for scholar review.
