So long you will have this material body, you will have to suffer. You cannot avoid it. Mātrā-sparśās tu kaunteya śītoṣṇa-sukha-duḥkha-dāḥ (BG 2.14). That is stated in the Bha... Mātrā-sparśāḥ. What is the suffering? Suffering means on account of this body. The same water, it is very pleasing during summer, and the same water, it is very distressing in winter. So water is the same, but it is distressing and pleasing on account of this body. Very simple thing, one can understand. Mātrā-sparśās tu kaunteya śītoṣṇa-sukha-duḥkha-dāḥ. The water is neither pleasing nor distressing. It is due to my this body and bodily concepts of life, we are suffering or enjoying, so-called enjoying, so-called suffering. Actually, I am the spirit soul. I am different from this body, gross body and subtle body. I have no suffering, no, I mean to say, enjoying. It is simply my imagination. Therefore a mukta-puruṣa, a liberated person, he is not affected by this so-called suffering or enjoying. That is called liberation.
