Bhagavad Gita 2.14
Heat and cold, pleasure and pain are passing sense contacts, so Arjuna should learn to endure them.
मात्रास्पर्शास्तु कौन्तेय शीतोष्णसुखदुःखदाः।
आगमापायिनोऽनित्यास्तांस्तितिक्षस्व भारत॥
mātrāsparśās tu kaunteya śītoṣṇasukhaduḥkhadāḥ
āgamāpāyino 'nityās tāṃs titikṣasva bhārata
Translation
"Kaunteya, it is the touch of the senses on their objects that brings cold and heat, joy and sorrow. These arrive and depart and never stay, so learn to endure them, Bharata."
Hindi
"कौन्तेय, इंद्रियों का विषयों से स्पर्श ही सर्दी-गर्मी और सुख-दुःख देता है। ये आते हैं और चले जाते हैं, टिकते नहीं। भारत, इन्हें सहना सीखो।"
Commentary
Pleasure and pain are described as passing contacts of the senses with the world, which is why they cannot be the measure of what is real. The word titiksha, patient endurance, is not suppression: it means staying steady while the weather of experience changes. 2.15 names the reward of that steadiness.
