An answer to What is the sound of one hand clapping? is obvious
to any bald person (he said, clapping one hand on his/her forehead/
five head/six head.

A young zen buhddist monk is given a coan by his master, not
knowing that by intent, the question has no answer. It's purpose
is to wear out/wear down the ego enough to get it out of the
way of enlightenment.

The young monk meditates for an entire week - no sleep,l no food
and only a sip or two of water each day - the whole time he's really
leaning into it trying to come up with The Answer.

At the end of the week he asks his master for permission to commit
suicide, having failed so miserably and disgracing his master, his
monastary, hhis family and village. His master suggests he try
again - just for a day. If, by the morning of the second day, he still
hasn't gotten "it" he would be permitted to jump of the tall monastary
water tower - at sunrise.

The young monk returns to his cell and redoubles his effort to
answer the coan. As each hour passes he strains harder and harder,
stretching his mind and body beyond what he had thought were
their limits. Nothing.

In the cool crisp morning air the young monk begins his climb to
the top of the water tower - meditating for all he's worth trying
to come up with an answer.

Sitting on the edge of the water tower, waiting for the first
morning rays of sun to crest the mountains on the far side of
the valley from him he meditates for all he's worth - covered
in persperation and shuddering in the chilly air - grateful for
the slight breeze which cools him a little. The sounds of the
village below begin to reach him as the first cock crows,
anticipating the sunlight by moments.

The young monk tries desperately to find The Answer, realizing
what he's about to give up - to no avail.

And just as he's stepped off the tower - he got it!

- end of Zen joke -

As science explores the very small and the very large it's becoming
more and more apparent that Everything Is Everything might actually
be true - different manifestations of the whole.

So when one's ego gets sidetracked - and out of the way . . .
