So ācārya, guru, representative, it is not difficult. Simply one has to become very, very sincere. One must undergo the simple tapasyas as prescribed in the śāstra. Caitanya Mahā . . . yes. Haridāsa Ṭhākura. Āpani ācari prabhu jīvere śikhāya. He was preaching also the glorification of chanting Hare Kṛṣṇa by personal example; therefore he is accepted as guru. All the Vaiṣṇavas, all the ācāryas, Gosvāmīs, they acted accordingly and preached. Therefore they are ācāryas. And Kṛṣṇa says, ācāryaṁ māṁ vijānīyān nāva-manyeta karhicit (SB 11.17.27). These are the instructions.
So this Kṛṣṇa consciousness movement is there. It is very simple. There is no difficulty. We have to always . . . man-manā bhava mad-bhaktaḥ (BG 9.34). Now, for us, those who are materially attached, we cannot think twenty-four hours of Kṛṣṇa. It is very pleasing, but because we are materially attached, we cannot do that. Therefore Kṛṣṇa is prescribing that, "You see the varieties of this material world and try to remember Me." These are the varieties: puṇyo gandhaḥ pṛthivyāṁ ca, tejaś cāsmi vibhāvasau. "You study, nature study." Just like we study nature study, similarly, "You study nature and see these important points. And there I am." It is very scientific. You study nature and pick up some point, and Kṛṣṇa says that, "This is I am." Where is the difficulty? This is Kṛṣṇa consciousness. You drink water—you remember Kṛṣṇa. You see the light—remember Kṛṣṇa. You see the flavor, aroma of very nice flower, puṇya gandhaḥ—immediately remember Kṛṣṇa. Practice this. It is not difficult.
Actually, we have to think of Kṛṣṇa . . . Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. Always thinking of Kṛṣṇa. Man-manā bhava mad-bhaktaḥ. Here is Kṛṣṇa's form, therefore we have to worship Deity. Constantly, if we worship, then Kṛṣṇa's form is always impressed—I can see Kṛṣṇa any, any time. If I close my eyes, I will see Kṛṣṇa, how Kṛṣṇa is nicely dressed. I see Kṛṣṇa is very pleasingly eating what I have prepared with devotion, bhaktyā. Real thing is bhaktyā, not official. Not official. Patraṁ puṣpaṁ phalaṁ toyaṁ yo me bhaktyā prayacchati (BG 9.26). He does not accept anything even it is not offered with bhakti and by the bhakta. He does not accept. Why He shall accept? Is He hungry, like me? No, he simply wants to see how you have learned to love Kṛṣṇa—bhakti, how you are eager to serve Kṛṣṇa. That is . . . Kṛṣṇa want to see. Otherwise, He does not require your service. Lakṣmī-sahasra-śata-sambhrama-sevyamānam (Bs. 5.29). He's always being served by hundreds and thousands of goddess of fortune. They are so much afraid. They are goddess of . . . we are praying here goddess of fortune, "My mother, goddess of fortune, give me some fortune." They are . . . the goddess of fortune is afraid if Kṛṣṇa may reject. Just like Rukmiṇī. When Kṛṣṇa was joking with her, she thought, "Maybe Kṛṣṇa is going to leave me." Immediately fainted. Immediately fainted. That is the goddess of fortune. So humbly, so fearfully, they are engaged in Kṛṣṇa's service.
What Kṛṣṇa's service we can give? What we are? We are nothing. Insignificant. So why Kṛṣṇa accepts our service? Why He comes in His arcā-mūrti to accept our service? Just to induce you how to serve Him, bhakti. That is wanted. Therefore He says, "So you give Me even patraṁ puṣpaṁ phalaṁ toyam (BG 9.26). It doesn't matter. But give Me with bhakti." Yo me bhaktyā prayacchati. This is real business. If you have no bhakti, if you officially make, Kṛṣṇa does not touch it. Kṛṣṇa is not so poor. Lakṣmī-sahasra-śata-sambhrama-sevyamānaṁ govindam ādi-puruṣaṁ tam . . . (Bs. 5.29). So whatever you do, you should always be humble: "Kṛṣṇa, I am quite unfit. So whatever I could collect with my capacity, kindly accept." This is our only plea. Otherwise, don't be proud that "I am doing so much for Kṛṣṇa. Kṛṣṇa will be obliged to accept it." It is not like that. Tṛṇād api sunīcena taror api sahiṣṇunā (CC Adi 17.31 / CC Antya 20.21, Śikṣāṣṭaka 3). This is wanted.
