When we dance with Kṛṣṇa in the Goloka Vṛndāvana, both of us are enjoying. Kṛṣṇa is enjoying; we are also enjoying. But if we want to enjoy independent of Kṛṣṇa or to imitate Kṛṣṇa or to become Kṛṣṇa, then it is māyā. Then it is māyā. This material world means the same enjoying spirit is there within me, but if I want to become Kṛṣṇa or enjoy independently, then it is māyā. So therefore we should enjoy with Kṛṣṇa. That is the aim of. The same thing is there.
So Kṛṣṇa comes, therefore, personally appears and exhibits His enjoying love in Vṛndāvana. He brings His friends, His girlfriends, boyfriends, everything, His father, His mother, and shows that "The enjoyment which you are seeking, that is there in the spiritual world with Me. See how I am enjoying." Just so that we may have our brain clear that if we enjoy with Kṛṣṇa, we can enjoy the dance, the paternal love, the conjugal love, the friendly playing with boys, with animals, who is in the garden, in the forest, in the water—same thing is there. Everything is there, all the sporting, but spiritual. So this is Kṛṣṇa's līlā. Ānanda-cinmaya-rasa-pratibhāvitābhis (BS 5.37).
So we are seeking pleasure within this material world. That is imitation. That is not real enjoyment. But the basic principle of enjoyment is there. Here there is imitation enjoyment—love between young boy, young girl. So wherefrom it comes? It is there in Kṛṣṇa. Otherwise how it can come? It is not possible. Janmādy asya yataḥ (SB 1.1.1). This loving exchange between young boy, young girl is there. Kṛṣṇa is also enjoying there. The gopīs, the young girls, Kṛṣṇa is young... The exchange of love between father and son, mother and son; the exchange of love between friend and friend; the exchange of love between animal and man... We, just like we keep so many animals, Kṛṣṇa is also enjoying with the calves. Sometimes with other animal also. Same thing is there. It is simply imitation here. Otherwise, everything is there in the spiritual world. We are mistaking, here, karma-phala-vadya(?). But here is no inebrieties, in the spiritual world. Here it is full of inebrieties. You'll see that Kṛṣṇa is enjoying with the gopīs, but there is no inebriety. There is no pregnancy, there is no abortion. That is the beauty. And the material world, the love is turns into lusty desires, and it entails so many difficulties. Yan-maithunādi-gṛhamedhi-sukhaṁ hi tucchaṁ kaṇḍūyanena karayor iva duḥkha-duḥkham (SB 7.9.45). Here sex life means entailed with so many sufferings. But there is no sex life in the spiritual world, but the pleasure is there. That is the difference between material and spiritual. Therefore there is restriction. Just like sex life is there, but a tuberculosis patient, if he enjoys sex life, he'll die very soon. Without sex life he could live for some years. Everyone will die. So for tuberculosis patient sex life is strictly prohibited.
