Khalil Gibran - The Wise Dog

One day there passed by a company of cats a wise dog.

And as he came near and saw that they were very intent and heeded
him not, he stopped.

Then there arose in the midst of the company a large, grave cat and
looked upon them and said, 'Brethren, pray ye; and when ye have
prayed again and yet again, nothing doubting, verily then it shall
rain mice.'

And when the dog heard this he laughed in his heart and turned from
them saying, 'O blind and foolish cats, has it not been written and
have I not known and my fathers before me, that that which raineth
for prayer and faith and supplication is not mice but bones.'

Khalil Gibran
