We have some practical experience. Sometimes we find a person leaves all worldly engagements, leaves his family, gives up his family connection, becomes a renounced order, sannyāsī, and highest order, and then, after some time, he becomes engaged in opening hospitals and philanthropic work and in politics. We have seen it. Oh, why? You have renounced the world. Why you are hospital-making business? Hospital-making business is there, going on by the government, by the state. You are not meant for making hospitals. You have to make hospitals how people can get rid of this material body. That is spiritual activity.
We also require to open hospital. And what is that hospital? To cure this material disease, not this temporary disease. Again we may be attacked. The complete cure of material disea . . . that sort of hospital will be required. That hospital is this Kṛṣṇa consciousness Society. If we take treatment under this Kṛṣṇa consciousness Society, then we shall be cured of this material disease. Otherwise, we shall be again attacked with some kind of body. Vāsāṁsi jīrṇāni yathā vihāya (BG 2.22).
Just like we change our dresses from one dress to another, similarly, this body to another body, transmigration of the soul. But we are meant for now completely ceasing to have any material body in the next life. That should be our aim of life. That is called . . . that knowledge is called the purest knowledge. Na hi jñānena sadṛśaṁ pavitram iha . . . that knowledge is the purest knowledge.
