So they must have engagement. Because we small particles of the Supreme, we are also engaged... Kṛṣṇa-bahirmukha hañā bhoga vāñchā (Prema-vivarta). We are engaged in material affairs. So our business is to finish this material affair or not to be attracted by the material affairs, but to be attracted by the spiritual affairs. That is required. Not that finishing. It cannot be finished. Therefore in the śāstra (it) says, ye 'nye 'ravindākṣa vimukta-māninas tvayy asta-bhāvād aviśuddha-buddhayaḥ: (SB 10.2.32) "Those who are thinking that 'Now we have brahma-jñāna, knowledge, and we have become one with Brahman, therefore we are now liberated,' vimukta-māninaḥ, that is not liberation." The liberation is not there because tvayy asta-bhāvāt, because the senses are not yet engaged in the service of the Lord." They do not know the Personality of... Tvayy asta-bhāvād aviśuddha-buddhayaḥ. They cannot be liberated.
Why not? They have already become liberated? No. Āruhya kṛcchreṇa paraṁ padaṁ tataḥ patanty adho 'nādṛta-yuṣmad-aṅghrayaḥ (SB 10.2.32). Āruhya. They have undergone severe penances, austerities. That is right. And they have come to the paraṁ padam, brahmapāda, but patanty adhaḥ, because... ānandamayo 'bhyāsāt (Vedānta-sūtra 1.1.12). Everyone wants ānanda, and part and parcel of ānanda, Kṛṣṇa, he wants ānanda. So simply realization, ahaṁ brahmāsmi, will not stay, will not stay. Because simply knowing "I am such and such," simply knowing that "I am a millionaire," or simply knowing that "I am a big man," that will not help him. He must also have activities. Ānandamayo 'bhyāsāt. Abhyāsāt means there must be activities. If you stop activities, there will be no ānanda. Then you will again search out where is activities. And because you have no spiritual activities, you will come down to the material activities.
