Therefore this Kṛṣṇa consciousness movement is to make people free from all sinful activities. Then they will be happy. Because in the soul proper, it is pure. Just like you contaminate some disease, so you suffer. You have got fever, you have got some pain. So you have to go to the physician. He will give you some medicine to counteract the contamination. Then you become happy. Similarly, we are all part and parcel of God, Kṛṣṇa. Naturally, we must be happy. Ānandamayo 'bhyāsāt (Vedānta-sūtra 1.1.12). This is our position, that we must be always ānandamaya, jubilant. This is our position. Just like Kṛṣṇa is dancing—you have seen—similarly, our position is simply dancing with Kṛṣṇa and be happy. That is our position. But we have come to this material world to enjoy independently of Kṛṣṇa. Therefore we have been captured by the illusory energy.
kṛṣṇa-bahirmukha hañā bhoga vāñchā kare
nikaṭa-stha māyā tāre jāpaṭiyā dhare
As soon as we forget or defy to enjoy with Kṛṣṇa... Just like a big man, a rich man... So the rich man is enjoying along with the servants are also enjoying. The servants are not poor in a rich man's house. He is eating of the same thing. He is also riding on the same car with the master. Rather, the driver is in the front, and the master is in the back. So in this way we are part and parcel of Kṛṣṇa. Just like in a family, why you take the risk of family? For enjoyment. I am alone. I can remain happy. Now, why you take the wife? I know if I marry then there will be children, there will be so many responsibilities. But why you accept? For happiness. Similarly, Kṛṣṇa is the supreme happy person. So we are part and parcel of Kṛṣṇa. To remain with Kṛṣṇa always... And He becomes happy, we are happy. This is our position.
