Puja is the Sanskrit word for worship. Puja is the act of showing reverence to a god through invocations, prayers, songs and rituals. An essential part of puja for a Hindu devotee is making a spiritual connection with a deity. The Lord being not accessible to our eyes, ears, nose, touch and beyond the realm of the intellect, the ancients devised a method of bringing the Lord within the realm of the senses. By puja you will be in a position to inject the noblest thoughts in the subconcious.
