Moan is saying:

Clear, clear – clearest! I ran barefoot east and west – unnecessarily. Now, more lucid than the moon, the eighty-four thousand dharma gates! All open suddenly, just like the lucid moon.

It is in the dark that eyes probe earth and heaven,
In dream that the tormented seek present, past.
Enough! The mountain moon fills the window.
The lonely fall through, the garden rang with cricket song.

These are not ordinary poems. These are statements of something that cannot be said but still has to be said. You can sing it but you cannot say it, you can dance it but you cannot say it. It is in my gesture but it is not in my word. You can see it but I cannot show it to you.

Searching him took
My strength.
One night I bent
My pointing finger –
Never such a moon!

Searching him took my strength. I have searched so much that I am tired, it has taken all my strength. But one night it happened and it happened in a strange situation:

One night I bent my pointing finger –
Never such a moon!

My bent finger pointed to the moon, to myself. The moon is the symbol of your eternity, of your beauty, of your blissfulness.

Such a moon –
The thief pauses to sing.

The thief is always afraid, he moves very cautiously. But, Such a moon! The thief pauses to sing. The thief forgets that he is a thief, and he becomes a singer.
