If convex and concave reject each other, there is no hope for life. The power to flatten the mountain and raise the valley is the power of love. If they reject each other, then there is no meadow, no life and no human beings. The body is three-quarters water. Women cry in private, quietly.
Men rush out the door and cry out to the mountains and oceans.
When laughing, men expand and women shrink down. No matter what you may try or think, woman is woman, man is man. You cannot change your gender. Even when you make love, if the wife wants to take subjectivity, she will have to tell her husband to lay down and she will get on top. But then the seed will be lost and no children will come.
