Prabhupāda: That is explained in the Bhagavad-gītā: mātrā-sparśās tu kaunteya śītoṣṇa-sukha-duḥkha-dāḥ. Sukha-duḥkha-dāḥ
- mātrā-sparśās tu kaunteya
- śītoṣṇa-sukha-duḥkha-dāḥ
- āgamāpāyino 'nityās
- tāṁs titikṣasva bhārata
- (BG 2.14)
If one is engaged in his cultivation of spiritual life, then he should tolerate all these bodily pains and pleasure. Because they come and go. Just like you are medical man, you treat, some patient. Suppose he's attacked with fever. Everyone knows that fever has come; after some time, it will go away. So the one who is cultivating Kṛṣṇa consciousness, he's not very much disturbed with fever. He knows that it has come, it will go automatically. If we fast for few days. There is a Bengali proverb, jvaranpar ketanadali palab...(?) If you receive one unwanted guest and fever, you don't give him eat. Then it will go away. Unwanted guest, if you do not give him food, he'll go away. Even a fever also, if you don't eat, it will go automatically. So after all, these things come and go. The example is given, śīta-uṣṇa. Śīta means winter and uṣṇa means summer. As the summer comes and go, winter comes and go, so these kinds of sufferings, they come and go. So Kṛṣṇa is advising, tāṁs titikṣasva bhārata. Therefore a brāhmaṇa's qualification is titikṣa. Śamo damaḥ śaucaṁ titikṣa, toleration. They're not very much bothered with the bodily pains and pleasure. They come and go. They're engaged in real business, how to realize Brahman. So if one is engaged in the prime business of life, Brahman understanding, athāto brahma jijñāsā, for him these bodily pains and pleasure becomes minor things. Therefore, we see such examples, that one saintly person is living in the Himalayan mountain. There is snowfall, there is no proper place, still they live. Still, there are many.
