"Plato once said that when the soul rejects the flesh and yearns for the truth, that is the best moment," Li Shishi said with a smile, "but when the soul is infected by the sins of the flesh, the desire to pursue the truth will not be fulfilled. When humans do not have a strong need for the flesh, their minds are at peace. Physical interaction is an expression of the bestial in human nature, a nature that belongs to every living being. The reason humans are so-called higher animals is because humanity is stronger than bestiality in human nature, and spiritual interaction is beautiful and moral. So, you see, having all these 'desires' is like having an extra leg; just cut it off, and it will be fine."
