just reflecting on this...
the process of creation itself is a sacrifice... that is explained in the purusha suktha itself... so yagnya is held in high reverance by vedic people, ie., us...
and that is why probably a grihastha's duties are divided into pancha maha yagnyas - Brahma/Deva/Pithru/Manushya/Bhootha...
the concept of yagya , is the very basis of "ARYAN" culture or refined culture.
we don't have to give a lot, but if we make a practice to give a little as a daily practice. that'll overcome our stinginess and misery overtime.
this lopa buddhi is - the major obstacle for any growth..
