Six in the fifth place means

Tears in floods, sighing and lamenting.

Good fortune.

Here the zenith of life has been reached. Were there no warning, one would at this point consume oneself like a flame. Instead, understanding the vanity of all things, one may put aside both hope and fear, and sigh and lament: if one is intent on retaining his clarity of mind, good fortune will come from this grief. For here we are dealing not with a passing mood, as in the nine in the third place, but with a real change of heart.
