ÅrÄ«la Baladeva VidyÄbhÅ«á¹£aá¹a, a great commentator on the Bhagavad-gÄ«tÄ, writes as follows: ye indrÄdy-aá¹ gatayÄvasthitaá¹ yajÃ±aá¹ sarveÅvaraá¹ viá¹£á¹um abhyarcya tac-cheá¹£am aÅnanti tena tad deha-yÄtrÄá¹ sampÄdayanti, te santaá¸¥ sarveÅvarasya yajÃ±a-puruá¹£asya bhaktÄá¸¥ sarva-kilbiá¹£air anÄdi-kÄla-vivá¹ddhair ÄtmÄnubhava-pratibandhakair nikhilaiá¸¥ pÄpair vimucyante. The Supreme Lord, who is known as the yajÃ±a-puruá¹£a, or the personal beneï¬ciary of all sacriï¬ces, is the master of all the demigods, who serve Him as the different limbs of the body serve the whole. Demigods like Indra, Candra and Varuá¹a are appointed ofï¬cers who manage material affairs, and the Vedas direct sacriï¬ces to satisfy these demigods so that they may be pleased to supply air, light and water sufï¬ciently to produce food grains. When Lord Ká¹á¹£á¹a is worshiped, the demigods, who are different limbs of the Lord, are also automatically worshiped; therefore there is no separate need to worship the demigods. For this reason, the devotees of the Lord, who are in Ká¹á¹£á¹a consciousness, offer food to Ká¹á¹£á¹a and then eat â a process which nourishes the body spiritually. By such action not only are past sinful reactions in the body vanquished, but the body becomes immunized to all contamination of material nature. When there is an epidemic disease, an antiseptic vaccine protects a person from the attack of such an epidemic. Similarly, food offered to Lord Viá¹£á¹u and then taken by us makes us sufï¬ciently resistant to material affection, and one who is accustomed to this practice is called a devotee of the Lord. Therefore, a person in Ká¹á¹£á¹a consciousness, who eats only food offered to Ká¹á¹£á¹a, can counteract all reactions of past material infections, which are impediments to the progress of self-realization. On the other hand, one who does not do so continues to increase the volume of sinful action, and this prepares the next body to resemble hogs and dogs, to suffer the resultant reactions of all sins. The material world is full of contaminations, and one who is immunized by accepting prasÄdam of the Lord (food offered to Viá¹£á¹u) is saved from the attack, whereas one who does not do so becomes subjected to contamination.
Food grains or vegetables are factually eatables. The human being eats different kinds of food grains, vegetables, fruits, etc., and the animals eat the refuse of the food grains and vegetables, grass, plants, etc. Human beings who are accustomed to eating meat and ï¬esh must also depend on the production of vegetation in order to eat the animals. Therefore, ultimately, we have to depend on the production of the ï¬eld and not on the production of big factories. The ï¬eld production is due to sufï¬cient rain from the sky, and such rains are controlled by demigods like Indra, sun, moon, etc., and they are all servants of the Lord. The Lord can be satisï¬ed by sacriï¬ces; therefore, one who cannot perform them will ï¬nd himself in scarcity â that is the law of nature. YajÃ±a, speciï¬cally the saá¹ kÄ«rtana-yajÃ±a prescribed for this age, must therefore be performed to save us at least from scarcity of food supply.
