Yagna is a manifestation of Vishnu. If the envelope properly addressed and placed in the mail box, it can be delivered to any village. With the aid of a mantra as a form of address, the sacred puja dravyas and cow ghee that are offered in the yagnakunda reach the Lord, who is the embodiment of truth.

This way of speaking is commonplace today that offering Ghee in Fire deemed foolish. Fools are the critics who think that way. The farmer dumps four sacks of paddy grains into the soil. I mean, who would have guessed that four bags of Paddy Grains would end up in the muck? Four months from now, he can harvest forty bundles of paddy by scattering a few handfuls in the mud. That describes Yagna, too. Yagna is a manifestation of Vishnu. It is not "waste," but "taste" for God!
