A poem by Jelaluddin Rumi...

When the time comes for the embryo

     to receive the spirit of life,

 at that time the sun begins to help.

This embryo is brought into movement,

    for the sun quickens it with spirit.

 

From the other stars this embryo

   received only an impression,

     until the sun shone upon it.

 How did it become connected

        with the shining sun

            in the womb?

 

   By ways hidden from our senses:

  the way whereby gold is nourished,

the way a common stone becomes a garnet

          and the ruby red,

     the way fruit is ripened,

  and the way courage comes

        to one distraught

             with fear

 

(I,3775-82)
