Bhagavad Gita 2.14 · Krishna
Cold and heat come and go
मात्रास्पर्शास्तु कौन्तेय शीतोष्णसुखदुःखदाः।
आगमापायिनोऽनित्यास्तांस्तितिक्षस्व भारत॥
mātrāsparśāstu kaunteya śītoṣṇasukhaduḥkhadāḥāgamāpāyino’anityāstāṃstitikṣasva bhārata
Son of Kunti, cold and heat, pleasure and pain come from the senses. They come and go. Bear them patiently.
What it means
Krishna gives a practical teaching. Every feeling arises when the senses touch the world. Heat and cold. Pleasure and pain. And all of them pass. He doesn't say ignore them. He says titikshasva, endure them, let them move through without being swept away.
The story
Arjuna is drowning in sorrow. Krishna reminds him that sorrow is weather, not climate. The same man who shivered in the Himalayas during exile and sweated in the forests survived all of it. This storm will pass too.
In your life
Picture someone on a long-haul flight with a crying baby nearby, stuck for twelve hours. Annoyance rises, peaks and fades. Next time a hard feeling comes, say to yourself, this is passing through. Then breathe.
Feelings are weather, not climate.
