Now we are under the control of this external energy, material energy. We have become controlled, just like we become controlled by the prison authorities when we are criminals, not ordinarily. Ordinarily we are free. Those who are not within the walls of prison house, they are free. They are acting wherever they like they are going, but within the law. Similarly we have got freedom. There are living entities, their number is greater. Nitya-mukta, ever liberated. They live in the spiritual world, Vaikuṇṭha planets. Nitya-mukta. Nitya-mukta means eternally liberated. They never come down in this material world. And we are nitya-baddha-ever conditioned, eternally conditioned.
Eternally conditioned means... We cannot be eternally conditioned, because we are part and parcel of Kṛṣṇa. Our natural position is ever liberated, eternally liberated. But because we wanted to imitate Kṛṣṇa, we wanted to become Kṛṣṇa, as the Māyāvādīs want to do, therefore in the spiritual world, Kṛṣṇa is the only enjoyer. Ekam eva aditiyam(?). Aham, bhoktāraṁ yajña-tapasāṁ sarva-loka-maheśvaram (BG 5.29). Sarva-loka, not only of the Vaikuṇṭhalokas, planets, but these planets also. Everywhere, Kṛṣṇa is the supreme proprietor. Therefore he is the supreme enjoyer. We cannot be enjoyer. We each can simply be servitor; that is our natural position. Just like a dog, when it serves a nice master, he's happy. Otherwise, it is street dog. Nobody cares for it. Street dog. A street dog has no position. Sometimes they are killed. Similarly, when we live under the full protection of the Supreme Lord, that is our healthy condition, that is our real life. And as soon as we give up this position to be subordinate, to be predominated by the Supreme Lord, then we are bewildered. We are thrown into this, under the control of this material nature, and according to our work we get different bodies. There are 8,400,000 forms of bodies and we get one body after another. Tathā dehāntara-prāptir dhīras tatra na muhyati (BG 2.13). This is called ever conditioned. Caitanya Mahāprabhu says ei rūpe brahmāṇḍa bhramite kona bhāgyavān jīva guru-kṛṣṇa-kṛpāya pāya bhakti-latā-bīja (CC Madhya 19.151). In this way, we are wandering from one species of life to another, one planet to another. In this way the brahmāṇḍa, this universe is very very big and there is immense opportunity. You become sometimes demigod, sometimes dog, sometimes cat, sometimes tree. In this way, we are wandering.
