Bhagavad Gita 2.14

मात्रास्पर्शास्तु कौन्तेय शीतोष्णसुखदुःखदाः।आगमापायिनोऽनित्यास्तांस्तितिक्षस्व भारत ॥२.१४॥

mātrāsparśāstu kaunteya śītoṣṇasukhaduḥkhadāḥāgamāpāyino’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.
