Thinking links up sense data with words, following the wishes or motivations and impulses. Thinking has a beginning and end, visualized in the image of burning wood. You should not think beyond the solution of the problem. The motivation is to attain clarity, unattached to the thought. Thinking, like dialogue, is not an end in itself.
Feelings experience the inner signals, as opposed to the outer signals of senses.
The image is the clear lake which you can look through. The motivation is serenity, to be joyous together, and not to be together in pity or sympathy, which means emphatic suffering with the another. The image is the vastness of our planet. The motivation is the receptive, to receive the germ and let it grow. The first four trigrams are Yin, they result in emptiness of the functions.
