The highest yajna

The person who performs the yajna of knowledge makes a greater sacrifice than another who performs the yajna of money,for the yajna of knowledge covers everything,money and all other things.Knowledge covers everythg which exists in the world,with out reference to the distinction betwen living and non-living.If we understand the terms dravya and janana in a wide sense,a yajna of knowledge includes yajna of every kind of dravya.Anyone who imparts the highest knowledge to us,convinces us to the very depth of our being that the body is not the atman,performs a very great yajna indeed
