Srimad Bhagavad-Gita :
Chapter-3. ( Karma-yogam )
Slokam-13. ( The devotees of the Lord are released from all kinds of sins because they eat food ( the balance of yjnam ie; prasadham ) which is offered first for yajnam. Others, who prepare food for personal needs and satisfactions, verily eat only sin. )
Yajnasishtasinah santo mucyante sarvakilbishaih,
Bhunjate te tvagham papa ye pacantyatmakaranat.
yajnasishtasinah santah = the prasadham taken by the devotees after the event
sarvakilbishaih mucyante = they (the devotees) get relief from all kinds of sins;
ye atmakaranat = those who for their own need only;
pacanty = prepare (cook) food;
te papah tu = but those sinners (who cook food for their need only);
agham bhunjate = they eat sin only.
Therfore those that only eat food that has been offered in yagna or worship are faultless and no other. This Lord Krishna is confirming with the word santah meaning saintly and virtuous. Those who perform yagna become absolved of all sins produced from the daily use of the five utensils in the home used by householders in the cooking and preparing of foods. Such sins are produced from the non-performance of the injunction of yagna and from the performance of the prohibited action. These are serious hindrances in attaining heaven. The five acts if piety performed by the twice born brahmins are mandatory, beginning with Brahma Yagna or Vedic study, offering worship to God, homage to the anscestors, feeding of animals and welcoming and feeding chance guests. These five acts of piety neutralise all sins contracted by the five areas of destuction in the home being the pestle, the grindstone, the fireplace, the waterpot and the broom. Manu Samhita III. 69-71 confirms all sins from these five actions are duly nullified by the five previous acts of piety.
Those who prepare food from funds honestly acquired with the sole objective of worshipping the Supreme Lord Krishna who resides as the soul within themselves as well as within all the demi-gods and every living entity; and those who only partake of such duly consecrated food become absolved of all sins accumulated over iniquity subatomic and atomic impending the completion and fulfilment of self realisation of the atma or soul. But those sinful wretches who do not first offer to the Supreme Lord what was gifted to them and instead prepare and eat it appropriating it for theirselves verily eat only sin. The word agham meaning sin denotes their will be grave consequences for such sins. Ignorant of the path to atma- tattva or self realisation of the soul, such degraded persons perpetually eat sinful food insuring a hellish destination in their next life. It should be understood that everything is connected to yagna or worship in this world and the next, from both the point of view of sastra or Vedic scripture and from inference. It should also be clearly understood that the observance of yagna is essential for benefit and welfare of all mankind and that its omission purposefully or accidental is counter productive for the entire human race and is fraught with sinfulness and dire consequences.
Therefore it can be understood that those humans who perform yagna or worship to the Supreme Lord Krishna are pre-eminent among the human species and not others. This is shown by the word santah meaning they are saintly and virtuous. Those who accept food after first offering it to the Supreme Lord are freed from the sins acquired from the five areas in the home causing harm to any living entity. They are: the mortar and pestle where sometimes extremely small bugs are accidentally killed, the grindstone where microscopic amoebas inside of the seeds are ground to death, the fireplace where sometimes crawling things come into when the fire is out only to be burned to death when the fire is lt, the waterpot where sometimes insects fly into and drown and the broom which while sweeping dirt and dust from the house might also sweep ants and such in such a way as to cause their demise. These are the five areas of harm in the home causing accidental death to harmless creatures as confirmed in the Manu Samhita III. 68. Those sinful wretches who do not first offer what they eat to the Supreme Lord are not freed from any of these sins but they are punished for them and verily day by day they eat only sin. On account of these sins multiplying daily they have no opportunity to attain heaven.
