Unmoving, the Self moves,

Moving, it remains ever still.

How is it known -

That which is beyond all joy and sorrow

And yet is embodied in both the joyful and the sorrowing

One who meditates on that Self

Which is formless in the midst of all forms,

Eternal in the midst of the momentary,

Which is everywhere at once ...

Such a one will know that Self

And finally cease grieving.

   - The Katha Upanishad 2:21 and 22
