Mind precedes all phenomena,
mind matters most, everything is mind-made.
If with an impure mind
one performs any action of speech or body,
then suffering will follow that person
as the cartwheel follows the foot of the draught animal.
Mind precedes all phenomena,
mind matters most, everything is mind-made.
If with a pure mind
one performs any action of speech or body,
then happiness will follow that person
as a shadow that never departs.
