(from Bhagavad Gita 4.24 & 15.14)

Meaning:

The whole Creation being a gross projection of Brahmam, the Cosmic Conciousness itself; the food too is Brahmam,the process of offering it is Brahman; it is being offered in the fire of Brahman. He who thus sees Brahman in action, reaches Brahmam alone.

I, the Supreme Spirit, abiding in the body of living beings as the Fire (Vaisvanara) in their stomach I am associated with their Prana and Apaana, digest the four types of food (solid, fluid, semifluid and liquid) which they eat.

These stanzas from the Bhagavad Gita guard us against the intake of food by making us aware that, firstly, food is not in tended merely to appease the endless demands of our senses of taste and smell and, secondly, that, with the right remembrance of the Divine in everything, the act of taking food can be an excellent Sadhana or spiritual exercise. If we thus remember the Divine and then start eating the food, then the food also gets purified and becomes a "Prasad" or gift of God.
