Keep it physical

Meditation has to be a physical exercise; a mental exercise would make the mind busy, and therefore not thoughless, which is the goal of meditation.

Meditation

In ancient times of crisis,
Those who meditated well did not think
Those who thought well did not fret
Those who fretted well did not agonize
Those who agonized well did not despair
Those who despaired well did not lose their mind
To the Medicine Men.
