On the surface, its definition is different in a Mantra to Mantra, and even worse in the

Mahayana Mantra, the description such as “Exist as not exist” kind appeared so often.

——–? ? ? Then oneday, I suddenly realized, the matter is not on the superficial words,

BUT in the intention behind of such expression.

At the teaching, Buddha wanted to show how uncertain the existences are, let alone

unreliability of our own perception, which supposed to observe and sense the objects.

Especially in the bottom line of the idea “Karma”, everything, include our 5 senses

are the relative phenomenon. Both observer and the observed.

Nothing can be certain.

——- In order to make Disciples to contemplate this, by themselves,

the Buddha must have used quite mind boggling, puzzling analogy.

YET, the understanding of the uncertainty itself, even the Self is exist or not was

not the main issue.

(Then I realized, this is the very situation which 1000 years old cliche has mocked

about while describing  ” See the finger, but not the moon “.

And, mocking the novice who is trapped into arguing the shape of the finger

such as ” Who is watching ” or ” Where they are ” kind, as ” Trying to catch Namazu

(slippery, slimy Cat-fish) by Hyotan (equivalent of smooth glass bottle).

——This is the very reason why all the famous answer to the  Koan  is, in fact,

mocking back to the question. )

What Buddha wanted to teach was, to brake the attitude of the people who

tend to cling or obsessed with the things or ideas.

Buddha wanted the people to have clear eyes to see the truth of the life.

Imposing self or distorting vision of the ego is the main obstacle to see

the truth.
