Sub-commentary: This explains the name of the hexagram based on the lines: because Six at the Beginning, a single yielding line, meets five firm lines above, it is named 'Meeting,' which is used to explain the hexagram judgment: 'The woman is bold; do not take the woman.'
From 'Do not take the woman' to 'all things become radiant.' Sub-commentary: 'Do not take the woman, one cannot endure with her for long': the proper nature of a woman is gentle, compliant, chaste, and obedient; only then can one hope to grow old together.
Being licentious and forward like this, one cannot remain with her for long; hence 'do not take the woman.' 'Heaven and earth meet each other, and all things become radiant': below, this broadly clarifies the meaning of meeting.
The hexagram derives the name Meeting originally from one yielding line meeting five firm lines; hence the judgment text is not flattering, taking from the hexagram to say meeting should not be used, which is 'do not take the woman.'
Therefore Confucius further looks to heaven and earth to praise the meaning of 'Meeting' as something that cannot be abandoned.
If heaven and earth were each to stay stubbornly apart without meeting, the myriad kinds of things would have no way to be manifested; the two qi must meet before transformation and birth can occur; hence 'heaven and earth meet each other, and all things become radiant.'
Sub-commentary: Master Zhuang says: 'One woman meeting five men cannot be taken, yet heaven and earth matching can complete all things.'
Speaking from this, if the firm meets yielding that is central and correct, and the man obtains a secluded, chaste woman, then the transformation of human relations under heaven will be practiced on a grand scale. 'Great indeed is the time and meaning of Coming to Meet!'
Sub-commentary: Having broadly praised it above, here he concludes with an exclamation of admiration, intending to draw meaning from the hexagram.
Although one woman meeting five men is not worthy of praise, broadly discussing 'heaven and earth meeting each other' brings about 'all things becoming radiant,' and only then is 'the time and meaning of Coming to Meet great indeed!'
Note: 'Whenever meaning is mentioned' to 'within it lies a deeper intended meaning.' Sub-commentary: The note sets forth a general rule for praising 'meaning,' hence saying 'whenever.'
Examining the name and meaning through the hexagram, it is merely a woman meeting a man; but broadly seeking the profound purport of meeting, it extends to the Dao encompassing heaven and earth; hence it says: 'it is not exhausted by what is seen, within it lies a deeper intended meaning.'
