SB 9.14.47
tenayajata yajñesam
bhagavantam adhoksajam
urvasi-lokam anvicchan
sarva-devamayam harim
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
By means of that fire, Pururava, who desired to go to the planet where Urvasi resided, performed a sacrifice, by which he satisfied the Supreme Personality of Godhead, Hari, the enjoyer of the results of sacrifice. Thus he worshiped the Lord, who is beyond the perception of the senses and is the reservoir of all the demigods.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
As stated in Bhagavad-gita, bhoktaram yajña-tapasam sarva-loka-mahesvaram: any loka, or planet, to which one wants to go is the property of the Supreme Personality of Godhead, the enjoyer of the performance of sacrifice. The purpose of yajña is to satisfy the Supreme Personality of Godhead. In this age, as we have explained many times, the yajña of chanting the Hare Krsna maha-mantra is the only sacrifice that can satisfy the Supreme Lord. When the Lord is satisfied, one can fulfill any desire, material or spiritual. Bhagavad-gita (3.14) also says, yajñad bhavati parjanyah: by offering sacrifices to Lord Visnu, one can have sufficient rainfall. When there is sufficient rainfall, the earth becomes fit to produce everything (sarva-kama-dugha mahi). If one can utilize the land properly, one can get all the necessities of life from the land, including food grains, fruits, flowers and vegetables. Everything one gets for material wealth is produced from the earth, and therefore it is said, sarva-kama-dugha mahi (Bhag. 1.10.4). Everything is possible by performing yajña. Therefore although Pururava desired something material, he factually performed yajña to please the Supreme Personality of Godhead. The Lord is adhoksaja, beyond the perception of Pururava and everyone else. Consequently, some kind of yajña must be performed to fulfill the desires of the living entity. Yajñas can be performed in human society only when society is divided by varnasrama-dharma into four varnas and four asramas. Without such a regulative process, no one can perform yajñas, and without the performance of yajñas, no material plans can make human society happy at any time. Everyone should therefore be induced to perform yajñas. In this Age of Kali, the yajña recommended is sankirtana, the individual or collective chanting of the Hare Krsna maha-mantra. This will bring the fulfillment of all necessities for human society.
