People who have truly seen the world have a gray mindset, and even a rainbow-colored one. They can understand the logic of pirates as well as that of saints. Those who reach the top and begin to return to cultivation are extremely humble and easygoing. They put away their sharpness and arrogance, leaving gentleness and decency for everyone they meet. They have a profound reverence for the laws of heaven and earth. They know that in the face of the great trend of the times, a person is no more than a speck of dust, and no one can escape the cycle of harvest. The ultimate return to simplicity: those who have truly seen the world have tasted all the delicacies of life, only to find that the best is still a bowl of plain porridge at home; they have worn all the beautiful clothes of the world, only to find that the most comfortable is a plain cotton T-shirt; they have experienced all the prosperity of the world, only to find that the most precious thing is the ray of sunlight on their body. This is called the brilliance of the extreme returning to simplicity. They no longer seek excitement, novelty, or others’ approval. They begin to look inward. They start to enjoy solitude, daydreaming, and dialogue with their own soul. They become very simple, pure, and even a bit like a child. But this child is a newborn after experiencing vicissitudes and crossing storms. When you have traveled through thousands of mountains and rivers, and finally return to the starting point, seeing your original self, at that moment, you have truly seen the world.
