Those who are devotees, they are allowed to enter into the planet, Vaikuṇṭha planet or Goloka Vṛndāvana planet. In this way one gets his original position. But if we do not take to bhakti, then we may enter into the Brahman effulgence, but there is chance of falling down. Āruhya kṛcchreṇa paraṁ padaṁ tataḥ patanty adho 'nādṛta-yusmad-aṅghrayaḥ (SB 10.2.32). So those who are impersonalist, they may enter into the spiritual kingdom. That is called paraṁ padaṁ. Padaṁ padaṁ yad vipadāṁ na teṣām (SB 10.14.58). But there is also chance of falldown. Āruhya kṛcchreṇa. After severe austerities and penances one can enter into the Brahman effulgence. But unless one gets information of the paraṁ padaṁ—samāśritā ye pada pallava plavam—there is chance of falling down. In the material world there is bhūtvā bhūtvā pralīyate (BG 8.19).
But in spiritual also, if you enter into the spiritual kingdom, from there also, even sometimes it so happens. Of course, that is by God's desire. Just like Jaya-Vijaya. They were personal associates. But the explanation is Kṛṣṇa wanted that "They should go . . . the Hiraṇyakaśipu . . . these two, Jaya-Vijaya, they should go to the material world, and I must fight with them." Because that fighting, to become angry, that tendency is there. Where He will exhibit? In the Vaikuṇṭha there is no chance of exhibiting this anger and fighting. That is not possible. Therefore He induces His devotee to "Go to the material world and become My enemy, and I shall fight. I shall become angry," because in the Vaikuṇṭha, spiritual kingdom, there is no chance. Everyone is serving; everyone is friendly. Some relation . . . Where is the question of fighting? But fighting spirit is there; anger is there. Where He shall exhibit? And therefore Kṛṣṇa incarnates, He becomes angry, and a devotee becomes enemy, and this is Kṛṣṇa-līlā, nitya-līlā. It is going on.
