Śrīmad-Bhāgavatam 9.20.24-26
Blended reading (Sanskrit + English inline)
As indicated here by the words dauṣmanter agniḥ sācī-guṇe citaḥ, Bharata, the son of Mahārāja Duṣmanta, arranged for many ritualistic ceremonies all over the world, especially all over India on the banks of the Ganges and Yamunā, from the mouth to the source, and all such sacrifices were performed in very distinguished places. As stated in Bhagavad-gītā (3.9) , yajṣārthāt karmaṇo ’nyatra loko ’yaṁ karma-bandhanaḥ: “Work done as a sacrifice for Viṣṇu has to be performed; otherwise work binds one to this material world.” Everyone should engage in the performance of yajṣa, and the sacrificial fire should be ignited everywhere, the entire purpose being to make people happy, prosperous and progressive in spiritual life. Of course, these things were possible before the beginning of Kali-yuga because there were qualified brāhmaṇas who could perform such yajṣas. For the present, however, the Brahma-vaivarta Purāṇa enjoins:
aśvamedhaṁ gavālambhaṁ sannyāsaṁ pala-paitṛkam devareṇa sutotpattiṁ kalau paṣca vivarjayet
“In this Age of Kali, five acts are forbidden: offering a horse in sacrifice, offering a cow in sacrifice, accepting the order of sannyāsa, offering oblations of flesh to the forefathers, and begetting children in the wife of one’s brother.” In this age, such yajṣas as the aśvamedha-yajṣa and gomedha-yajṣa are impossible to perform because there are neither sufficient riches nor qualified brāhmaṇas. This verse says, māmateyaṁ purodhāya: Mahārāja Bharata engaged the son of Mamatā, Bhṛgu Muni, to take charge of performing this yajṣa. Now, however, such brāhmaṇas are impossible to find. Therefore the śāstras recommend, yajṣaiḥ saṅkīrtana-prāyair yajanti hi sumedhasaḥ: those who are intelligent should perform the saṅkīrtana-yajṣa inaugurated by Lord Śrī Caitanya Mahāprabhu.
kṛṣṇa-varṇaṁ tviṣākṛṣṇaṁ saṅgopāṅgāstra-pārṣadam yajṣaiḥ saṅkīrtana-prāyair yajanti hi sumedhasaḥ
“In this Age of Kali, people endowed with sufficient intelligence will worship the Lord, who is accompanied by His associates, by performance of saṅkīrtana-yajṣa. ” ( Bhāg. 11.5.32 ) Yajṣa must be performed, for otherwise people will be entangled in sinful activities and will suffer immensely. Therefore the Kṛṣṇa consciousness movement has taken charge of introducing the chanting of Hare Kṛṣṇa all over the world. This Hare Kṛṣṇa movement is also yajṣa, but without the difficulties involved in securing paraphernalia and qualified brāhmaṇas. This congregational chanting can be performed anywhere and everywhere. If people somehow or other assemble together and are induced to chant Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare, all the purposes of yajṣa will be fulfilled. The first purpose is that there must be sufficient rain, for without rain there cannot be any produce ( annād bhavanti bhūtāni parjanyād anna-sambhavaḥ ). All our necessities can be produced simply by rainfall ( kāmaṁ vavarṣa parjanyaḥ ), and the earth is the original source of all necessities ( sarva-kāma-dughā mahī ). In conclusion, therefore, in this Age of Kali people all over the world should refrain from the four principles of sinful life — illicit sex, meat-eating, intoxication and gambling — and in a pure state of existence should perform the simple yajṣa of chanting the Hare Kṛṣṇa mahā-mantra. Then the earth will certainly produce all the necessities for life, and people will be happy economically, politically, socially, religiously and culturally. Everything will be in proper order.
