What does it mean, 'inner' and 'outer' trigram (popup)
Kăn below Zhèn: Kăn often indicates intuition and the freeing of tensions because it has no shape of its own, and when it has Zhèn on the outside to manifest that, you get the immediate reaction power of acrobats. A freedom of thinking, moving, and split-second decisions that is not restrained by rules, ideas or fears.
Ideogram of the character Jiě: at the top two hands with a horn, at the bottom the head of an ox, but probably originally an arrow (with bow-string?) and the horn either an awl or an archer's thimble. Release, solution, opening bound and tied things, remove, abolish, stop, melt, clarify, analyze and explain, understand, reconciliation, negligent, relaxed, slack, encounter, to alleviate (pain etc); to cut apart, dissect, dissolve, discharge (water etc), defecate, to forward, send, hand over to. In the past, it referred to various skills of acrobatic performances, especially those performed on horses.
The Image says: Thunder and rain at work: release. The noble one pardons transgressions and is lenient towards crimes.
Hex.40 is the contrast of 37, which is about being and acting according to your abilities and to the place in life where you belong.
Hex.40 is when nothing is predefined, it is the moment and the intuïtion which decide the action. Hex.40 is the hexagram of the archer who releases the arrow at the right moment and exactly on its target. Not by aiming consciously but because nothing else exists for him right then.
