What does it mean, 'inner' and 'outer trigram' (popup)
Thunder below Lake: Lake is a confined space, the place 'where, and with who, it happens', the immediate environment. You have to reckon with it. It is not possible to make something happen outside of the space you can reach. Thunder, with all its energy, has to adapt to this reality. But if it is done well, it means being at ease with one's life and possibilities, making the best use of what it has to offer. Moving along in a smooth and meaningful way.
Ideogram of the hexagram name: the left part is a foot with a road: going. The right part is a (left: helper) hand with a tool and a piece of meat. In between is a height or mound. An image of hunting in a rough terrain. Meanings: to hunt, to follow, to trace, to come after, pursuit, along, compliance, follower, attendant, letting go, listen, listen to the call, immediately. When the 'mental' lines 3 and 6 change, there is hex.13: the one who reads the trails and classifies creatures.
The 'Great Image' says: In the center of the marsh is thunder: Following. The noble one, towards nightfall, goes inside to eat and relax.
Hex.17 is the contrast of 18, which is about changing things, spoiling them or cleaning them up. Turning them into how you want them to be.
Hex.17 sees how things are and follows the best way to deal with them or to live among them.
