Six in the Third is the third line of Progress, a yin line in a yang position at the top of the lower trigram Kun. 'All approve' — unanimous support, collective endorsement. When everyone around you recognizes and supports your advancement, all previous doubts and regrets vanish.
This is the breakthrough moment in Progress: after the initial holding back (First Six) and the anxious waiting (Six in the Second), here at last comes universal recognition. Your merit has become so evident that it commands consensus.
As the card depicts — a flock of birds gathering around a phoenix, all facing in the same direction. When your virtue is undeniable, even those who previously doubted rally to your support.
