11- Tai/ Peace/ Advance, changing lines 1,4, and 6 to 50- Ding/ The Cauldron
(interesting that hexagram 11 is associated with the first month of the lunar year, which indeed is February; 50- Ding/ Cauldron is associated with the month of July)
Hex. 11- trigram placement: Kun/ Earth over Qian/ Heaven (earth supported by heaven)
Huang says (p 121): "In this gua, the significance of the union of Heaven and Earth is employed to display the importance of union among people. When people communicate sincerely and truthfully, harmony is created, and things will be achieved easily and smoothly...To the Chinese, the opposite of Tai is Pi. To go from Tai (Advance) to Pi (Hindrance) or vice versa is a natural law, as is the waxing and waning of the moon. The wise prefer to live in harmony with the laws of Nature. Be content with one's fate, and never blame Heaven or others."
Line 1 is about the good fortune of moving harmoniously with like minded people.
Line 4 is about being sincere in your associations with humility and respect; not acting lightly (like a fluttering bird)
LIne 6 is about the time of peaceful advance about to change to its opposite, indicating a new phase, or the need to be patient for the next phase to become full.
Hex. 50- trigram placement: Li/ Fire over Xun/ Wind (the power of fire carried forward on the wind)
Ding comes after the hexagram for Revolution, or what Huang translates as "Abolishing the Old". He explains that once a revolution had been won, the new leaders would do a ceremony using ceremonial serving dishes called Ding to establish the new order of society. The food in the ding would be served to honor the guests, the ancestors, and the Divine. "The ceremony symbolized the union of the family and the care of its members." (Huang p 398)
