Anyone who is engaged very seriously, satata-yuktānām, twenty-four hours, thinking, "Kṛṣṇa, how can I serve you...?" This is the only business. Man-manā bhava mad-bhakto mad-yājī māṁ namaskuru (BG 18.65). Four things: Always think of Kṛṣṇa... This Hare Kṛṣṇa means "O the energy of Kṛṣṇa, O Kṛṣṇa, please engage me in Your service. I have given service to this material world so much, but I could not satisfy the master, neither I am satisfied." Everyone is serving society, friendship, love, family, country, but none of them are satisfied. None of them sat... Even your President, he could not satisfy you. You had to drag him down. Neither he could satisfy himself. Even Gandhi could not satisfy his countrymen. Although he gave so much service, he was shot dead. So this is the material world. You cannot satisfy anyone, neither you become satisfied, materially engaged. This is called material world. We may show some artificial satisfaction, but there cannot be satisfaction in the material world. First of all, you have to take it as axiomatic truth that there is no happiness and there cannot be any satisfaction in this material world. Then you'll make, spiritually advance. If you have got little faith still that "I can be satisfied; I can be happy materially," then that is māyā's influence. That is māyā's influence. There is no possibility.
So if you want satisfaction, then you have to take to Kṛṣṇa consciousness. Compulsory: "You must." There is no other alternative. Therefore Narottama dāsa Ṭhākura sings, hari hari biphale janama goṅāinu: "My dear Lord Kṛṣṇa, I have simply wasted my time." Actually, anyone who has not taken Kṛṣṇa consciousness—simply wasting time. This is fact, scientifically true. But they do not know it. Māya-mohita. Mohitaṁ nābhijānāti mām ebhyaḥ param avyayam (BG 7.13). Being covered by the illusory energy, they do not know the background of this gigantic cosmic manifestation. That is Kṛṣṇa. So intelligence means to find out Kṛṣṇa. In the Īśopani..., Īśo, it is stated that "My dear Lord, please wind up Your, these dazzling rays so that I can actually see Your face." Within brahmajyoti the Kṛṣṇa is there. So Kṛṣṇa can be seen only by service. You cannot challenge Kṛṣṇa, "Kṛṣṇa, come here. I shall see You." No. That is not possible. You have to submit. Therefore Kṛṣṇa says, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). That is the way. You have to surrender. So long you don't surrender, that is up to you. Kṛṣṇa will not force you. He is almighty, He can force you, but He does not do that. He says, "You do this. If you do not do it, that is your business. But I say you do it."
