Every bird which flies has the thread of the infinite in its claw. Germination includes the hatching of a meteor and the tap of a swallow's bill breaking the egg, and it leads forward the birth of an earth-worm and the advent of Socrates.
I have read in books that we are called 'caged birds'. I cannot speak for others, but I had so much in this cage of mine that there was not room for it in the universe- at least that is what I then felt.
I read the Bible and know little of its history, but the human beings who wrote it were instruments of Divine Power, and Jesus forged a far stronger bond than the ten commandments: love.

In the case of the human being, things are more complicated because we know about love and its traps.
