Illusions...

We speak of the sky
and the ocean as being blue in colour,
but this is incorrect.

Neither the sky nor the ocean
are actually blue themselves.
It is the vastness of space and
the depth of the ocean that
produces this illusion of blueness.

If you take some seawater in your palm,
you will see that it is actually colourless.
Likewise, good and evil depend on our own thoughts and feelings.
