Indians make an offering of food to the Lord and later partake of it as prasaada - a holy gift from the Lord. In our daily ritualistic worship (pooja) too we offer naivedyam (food) to the Lord.
The Lord is omnipotent and omniscient. Man is a part, while the Lord is the totality. All that we do is by His strength and knowledge alone. Hence what we receive in life as a result of our actions is really His alone. We acknowledge this through the act of offering food to Him. This is exemplified by the Hindi words "tera tujko arpan"– I offer what is Yours to You. Thereafter it is akin to His gift to us, graced by His divine touch.
Knowing this, our entire attitude to food and the act of eating changes. The food offered will naturally be pure and the best. We share what we get with others before consuming it. We do not demand, complain or criticise the quality of the food we get. We eat it with cheerful acceptance (prasaada buddhi).
Before we partake of our daily meals we first sprinkle water around the plate as an act of purification. Five morsels of food are placed on the side of the plate acknowledging the debt owed by us to the Divine forces (devta runa) for their benign grace and protection, our ancestors (pitru runa) for giving us their lineage and a family culture, the sages (rishi runa) as our religion and culture have been "realised", aintained and handed down to us by them, our fellow beings (manushya runa) who constitute society without the support of which we could not live as we do and other living beings (bhuta runa) for serving us selflessly.
