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), yajñārthāt 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 yajña, 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 yajñas. For the present, however, the Brahma-vaivarta Purāṇa enjoins:

aśvamedhaṁ gavālambhaṁ
 sannyāsaṁ pala-paitṛkam
devareṇa sutotpattiṁ
 kalau pañca 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 yajñas as the aśvamedha-yajña and gomedha-yajña 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 yajña. Now, however, such brāhmaṇas are impossible to find. Therefore the śāstras recommend, yajñaiḥ saṅkīrtana-prāyair yajanti hi sumedhasaḥ: those who are intelligent should perform the saṅkīrtana-yajña inaugurated by Lord Śrī Caitanya Mahāprabhu.

kṛṣṇa-varṇaṁ tviṣākṛṣṇaṁ
 saṅgopāṅgāstra-pārṣadam
yajñaiḥ 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-yajña.” (Bhāg. 11.5.32) Yajña 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 yajña, 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 yajña 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 yajña 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.
