Karma is a concept encountered in several Eastern religions, although having different meanings.

Teachings about karma explain that our past actions affect us, either positively or negatively, and that our present actions will affect us in the future.

Buddhism uses an agricultural metaphor to explain how sowing good or bad deeds will result in good or bad fruit (phala; or vipāka, meaning 'ripening').

As you experience this pure love
what we all call "heart"
beams of light will begin to radiate from the center of it
for heaven is there in eternity.

If you can release this radiance of love
and allow it to flow through you,
your heart will become light.
The spirit will get liberated into the air
and then, from a place of inner stillness
you will know what it would be like
to be an eagle and soar in the evening skies.

And most of all,
you would understand
what it would be like 
to be perfectly sane.
