I want to ask why Jin Yong's "Sunflower Collection" says at the beginning that if you want to practice magic, you must first enter the palace.

Why did you write the sentence "If you want to practice magic, you must first enter the palace" at the beginning? Because this is a warning to future generations of sunflower collection! As a masterpiece, Sunflower Collection can deeply tap people's potential and make people's skills advance by leaps and bounds in a short time. However, while the potential is being explored, the human body's desire also explodes violently. In the end, the magical power was washed away by the expanding desire and possessed before it was reached! Therefore, removing the root of desire before practice becomes the basis of practice! "the way of heaven, the loss is more than enough to make up for the deficiency", so we must first become the "insufficient" body, and then take advantage of the trend to make up for ourselves!
