Phenomena are preceded by the heart,
ruled by the heart,
made of the heart.
If you speak or act
with a corrupted heart,
then suffering follows you -
as the wheel of the cart,
the track of the ox
that pulls it.

Phenomena are preceded by the heart,
ruled by the heart,
made of the heart.
If you speak or act
with a calm, bright heart,
then happiness follow you,
like a shadow
that never leaves.

Dhammapada 1-2
