In the Bhagavad Gita, there is no long discussion, nothing elaborate. The main reason for this is that everything stated in the Gita is meant to be tested in the life of every man; it is intended to be verified in practice.
Vinoba BhaveThe natural movement of one's soul is upwards. But just as any object is dragged down when a heavy weight is tied to it, the burden of the body drags down the soul.
Vinoba BhaveGross and subtle, pure and mixed, simple and complex - in the end that there is no place where God is not. In every atom, He alone is present. From the ant to the universe, He spreads. The Lord who cares equally for all, the compassionate one who is all knowledge, tenderness, skill, holiness and beauty - He stands on all sides everywhere.
