Kṛṣṇa wants to see how much you are devoted to Him. Dravya-yajña . . . Kṛṣṇa is not hungry that you have to offer something, very nice foodstuff. That is, you must do that. But if you have no such thing in possession, you can do it within the mind. But not that you have got everything to offer . . . you can offer Kṛṣṇa very nice foodstuff; in that case if you think that, "I can do it in mind," that is cheating. That will not be done. But in case you have nothing to offer materially, but still, you can offer in the mind. That is called vitta-sārtha. And actually we have seen in many places, a rich man has got Deity. The other day we went to a place, the Deity is there, but Deity is not worshiped. Deity is not offered anything. That is not good. That man is very rich man. According to his position, one must offer prepared foodstuff, distribute prasādam, not that . . . generally, the impersonalists, they do so. There are many big, big temples, big, big Deities, but the Deity is offered a little elaichi-dana. That is not good. If you establish Deity, you must worship to the best capacity of your possession. That is Deity worship. But if one hasn't got to offer anything, he can offer everything within the mind. This facility is there.
Therefore it is apratihatā, it cannot be checked, apratihatā. Because bhakti can be executed practically also within the mind. It cannot be checked. But if you have got something to offer to Kṛṣṇa, don't think that "I shall offer in my mind." That is . . . Kṛṣṇa is also very intelligent that, "He is cheating Me." Kṛṣṇa wants how much you are sacrificing in devotion, bhaktyā. Kṛṣṇa is not after your goods. That is explained in the Bhagavad, tad ahaṁ bhakty-upahṛtam aśnāmi. Patraṁ puṣpaṁ phalaṁ toyam (BG 9.26). Kṛṣṇa is prepared to accept from you even a little leaf, patram, even a little flower, patraṁ puṣpaṁ phalam, a little fruit. Anyone can secure these. Even if you cannot secure, if you are so poor or unable, you can offer Kṛṣṇa everything within the mind.
But if you are in possession, then that will not be successful. Then it will be cheating. That is called mithya-sārtha. According to one's means, ye yathā mām pra . . . according to one's position, they should worship Kṛṣṇa, maybe without any dravya or with dravya. Yajña is performed. Dravya-yajñās tapo-yajñāḥ. The svādhyāya. The Gosvāmīs, they also used to perform svādhyāya-yajña. That is also mentioned. Nānā-śāstra-vicāraṇaika-nipuṇau sad-dharma-saṁsthāpakau. They were studying all Vedic literature, all Vedic literature. That is called svādhyāya, svādhyāya-yajña, to read Vedic literature, to understand Vedic literature, to act according to the direction of the Vedic literature. This is called svādhyāya-yajña. Svādhyāya-yajña, jñāna-yajña. By reading Vedic literature, you enlighten yourself with knowledge. So this is also yajña. There are so many . . . Kṛṣṇa is available in so many ways, according to your position. It is not that He is conditioned. He is not conditioned. Therefore it is called ahaituky apratihatā. The svādhyāya-yajña.
The Gosvāmīs, they were not only dancing and chanting. That was also part of their business, kṛṣṇotkīrtana-gāna-nartana-parau. But they were also good scholars. Nānā-śāstra-vicāraṇaika-nipuṇau sad-dharma-saṁsthāpakau. Just like in our Kṛṣṇa consciousness movement, we are trying to publish our books in different languages. Already we have got in European and American, English, French, German, Spanish, Swedish, Japanese, Chinese. This is required.
Nānā-śāstra-vicāraṇaika-nipuṇau sad-dharma. Because people are misled. So they should be given opportunity to study, to understand what is God consciousness, what is Kṛṣṇa consciousness. So through the śāstras. That is also required. Nānā-śāstra-vicāraṇaika-nipuṇau sad-dharma . . . the Gosvāmīs practically demonstrated in their life everything. Caitanya Mahāprabhu taught them. They were the first disciples of Śrī Caitanya Mahāprabhu. Rūpa Gosvāmī was given lesson for ten days continually at Allahabad, Prayāga, Daśāśvamedha-ghāṭa. As a result of his instruction, he first wrote this Bhakti-rasāmṛta-sindhu, which we have translated into English, Nectar of Devotion. Similarly, Sanātana Gosvāmī was given instruction for two months at Benares, Vārāṇasī.
