Bhagavad Gita
Chapter 3: (Karma Yoga)
Krishna said:
9 Except that for the sacrifices
All other actions binds to world.
Hence to free from bondage do -
Actions as sacrifice oh Kawntheya!
10
Creating the mankind with sacrifice
Creator declared in the beginning
Sacrifice will be thy way to prosper
It is the milk-cow of thy desires too.
All actions are binding men as Karma. However, actions done as sacrifices do not bind, as it is offering to God. Further, it says that, at the time of creation the Creator declared; men do sacrifice to God. God's in return will bless you with all wealth. Thus sacrifices are the milk- cow, giver of desires.
Oh Lord, we will do our actions desireles and selflessly as sacrifices. Bless us.
