"One who engages in full devotional service, who does not fall down under any circumstance, at once transcends the modes of material nature and thus comes to the level of Brahman."
vadanti tat tattva-vidas
tattvam yaj-jnanam advayam
brahmeti paramatmati
bhagavan iti sabdyate
"Learned transcendentalists, who know the Absolute Truth, call this nondual substance Brahman, Paramatma or Bhagavan." The feature of the Supreme Personality is the ultimate realisation of God. He has all six opulences in full: He is the strongest, the richest, the most beautiful, the most famous, the wisest and the most renounced.
patram puspam phalam toyam
yo me bhaktya prayacchati
tad aham bhakty-upahrtam
asnami prayatatmanah
"If someone offers Me with love and devotion a leaf, a flower, a fruit or a little water, I will accept it." We offer Krishna only the kind of food He demands, and then we eat the remnants. If offering vegetarian food to Krishna were sinful, then it would be Krishna's sin, not ours. But God is apapa-vijna -- sinful reactions are not applicable to Him. He is like the dun, which is so powerful that it can purify even urine -- something impossible for us to do. Krishna is also like a king, who may order a murderer to be hanged, but who himself is not subject to punishment because he is very powerful. Eating food first offered to the Lord is also something like a soldier's killing during wartime. In a war, when the commander orders a man to attack, the obedient soldier who kills the enemy will get a medal. But if the same soldier kills someone on his own he will be punished. Similarly when we eat only prasada [the remnants of food offered to Krishna], we do not commit any sin. This is confirmed in the Bhagavad-gita (3.13):
yajna-sistasinah santo
mucyante sarva-kilbisaih
bhunjate te tu agham papa
ye pacanty atma-karanat
"The devotees of the Lord are released from all kinds of sins because they eat food that is first offered for sacrifice. Others, who prepare food for personal sense enjoyment, verily eat only sin."
