In the Vaikuṇṭha planets, the inhabitants, the citizens, they have got four hands. When Ajāmila was delivered by the Viṣṇudūtas, they appeared exactly looking like Viṣṇu. That is described. That is called sārūpya. Sārūpya, sārṣṭi (CC Madhya 6.266), same opulence. Or sāmīpya, always near, associate. There are five kinds of... Gacchanti tat-padam. But out of the five, the first one, namely to merge into the existence of the Supreme, that is very dangerous, not safe.
Therefore Vaiṣṇava never accepts sāyujya-mukti, to become one with the Supreme. Because Vaiṣṇava knows that impersonal advancement is risky. They know it perfectly. Therefore a Vaiṣṇava never... Vaiṣṇava is not anxious for any kind of mukti. Dīyamānaṁ na gṛhṇanti. They don't want... Especially Gauḍīya Vaiṣṇavas, they don't want mukti. They are happy wherever they are existing. If they get the chance of chanting Hare Kṛṣṇa mantra, that is perfection of life. They don't want anything more. Just like Haridāsa Ṭhākura. We should not imitate, but the position is like that. Just like Prahlāda Mahārāja. He was not at all afraid of this material world. He was very cautious. A spiritualist, a devotee, a Kṛṣṇa conscious person, should be very cautious. But not afraid to meet any dangerous position. But must be cautious. Cautious in this way, that he may not fall down again under the clutches of māyā. This should be, care should be taken.
