Letters of Sri Aurobindo
9. Fate and Free-Will, Karma and Heredity, etc
Fragment ID: 750
All energies put into activity – thought, speech, feeling, act – go to constitute Karma. These things help to develop the nature in one direction or another, and the nature and its actions and reactions produce their consequences inward and outward: they also act on others and create movements in the general sum of forces which can return upon oneself sooner or later. Thoughts unexpressed can also go out as forces and produce their effects. It is a mistake to think that a thought or will can have effect only when it is expressed in speech or act: the unspoken thought, the unexpressed will are also active energies and can produce their own vibrations, effects or reactions.
