What Kṛṣṇa says, that is practical. Annād bhavanti bhūtāni parjanyād anna-sambhavaḥ (BG 3.14). "How we shall get anna? There is no rain." You see nowadays, there is no rain. Why? Because you are . . . we are all rascals. We do not know how to get rain. Kṛṣṇa says, parjanyād anna-sambhavaḥ: "There will be food grains when there is sufficient rain." And how rain there will be? Yajñād bhavati parjanyaḥ (BG 3.14): "And if you perform yajña, then there will be sufficient rain." So nowadays you . . . people may say: "How to perform yajña? It requires so much money, so much ghee, so much food grains to offer as oblations." But Kṛṣṇa has made it very easy. Yajñaiḥ saṅkīrtana-prāyair yajanti hi sumedhasaḥ (SB 11.5.32). Yajñaiḥ saṅkīrtana-prāyaiḥ. I know, the śāstras know that in the Kali-yuga it will be very difficult to perform the ritualistic yajña ceremony because people will be poor, poverty-stricken. Where they will get ghee, and where they will get grains? No. This is yajña: kalau nāsty eva nāsty eva nāsty eva gatir anyathā. Harer nāma harer nāma harer nāmaiva kevalam (CC Adi 17.21). This is yajña.
So people are so rascal, they will not even chant Hare Kṛṣṇa mantra. Kṛṣṇa, svayaṁ bhagavān . . . Caitanya Mahāprabhu, He introduced. Saṅkīrtanaika-pitarau. Gaura and Nityānanda is the father of the saṅkīrtana movement. Therefore Vṛndāvana dāsa Ṭhākura has offered his prayer, saṅkīrtanaika-pitarau ājānu-lambita-bhujau kanakāvadātau, saṅkīrtanaika-pitarau kamalāyatākṣau (CB Ādi-khaṇḍa 1.1), vande mahā-puruṣa te caraṇāravindam. So Kṛṣṇa is teaching. Kṛṣṇa is so kind. He's personally teaching, that is, "Perform yajña." He's personally chanting, dancing, Caitanya Mahāprabhu. The picture is in our front. Personally He's teaching us, "Perform this yajña, you rascal, and you'll get everything. You'll get everything." Now, where is the proof? The proof is Kṛṣṇa consciousness movement. We are simply chanting Hare Kṛṣṇa mahā-mantra and spending crores of rupees. Simply. What we are doing? We are not doing any business. We have not many professional men. But why we are getting . . .? We are spending eight lakhs of rupees per month. And we have got food, we have got milk. We are, rather, feeding others also, bringing food. So why don't you see practically how these Kṛṣṇa conscious people . . . they . . . they know that we are fabulously rich. This question was raised in Parliament also. So how we became fabulously rich? We do not do anything. I have not taught you anything magic. I simply request you, "Chant Hare Kṛṣṇa mantra sixteen times, please." But you . . . we are not even following that. This is the only remedy. Yajñaiḥ saṅkīrtana-prāyair yajanti hi sumedhasaḥ (SB 11.5.32).
So Kṛṣṇa is the Supreme Personality of Godhead, Īśvara. He's teaching us this yajña. He's giving us the hint. Yajñād bhavati parjanyaḥ (BG 3.14). If you do not accept this Movement, then you'll go on suffering, suffering, suffering, suffering. If you don't accept this principle, then your future is simply suffering.
