मात्रास्पर्शास्तु कौन्तेय शीतोष्णसुखदुःखदाः |

“The transient sensations that your senses encounter—heat and cold, pleasure and pain—arise and pass away like the changing seasons. They are impermanent by nature. Therefore, learn to bear them with equanimity, remaining unmoved and unshaken by their coming and going.”

— BG 2.14
