In novels of middle and late Ming Dynasty, there are mainly two sorts of common Sexualized Aesthetic Perception of Avalokitesvara image: one is the secular kind, and that is, the appearance of Avalokitesvara image as secular beauty, a public object of phychosexuality; the other is the religious kind, which is normally shown in the Incarnation of Bodhisattva who would redeem people by bodily sacrifice, and yet unavoidly implied as the object of sexually joking, intentionally or unintentionally. There are four causes for the sexualized Aesthetic Perception of Avalokitesvara image. The first is the religious cause of this sexualization. Along With the feminization of Avalokitesvara image in Chinese Buddhism, her thirtytwo physical characteristics ,for certain reasons, had become a secular aesthetic standard, admired, or even coveted. Meanwhile, the original Buddhism idea of cultivating oneself by being polluted with desire had become a motif of novels long ago. The second is its social cause. In the middle and late Ming Dynasty, individual liberation was a prevalent social trend, and this sexualization is simply one of its special expressions. The Third cause is its gender aesthetics. In the middle and late Ming Dynasty, the feminization of male prevailed. This phenomenon has not only facilitated the feminization of Avalokitesvara image, but also eliminated the gender difference in the aesthetic perception, which gave this image a value of bisexual specimen.The fourth cause is in literature, and that is the strange evolvement of Avalokitesvara image on individual cases in Ming Dynasty literature, due to the antiauthority and antiascetic idea under the fall of the belief in Buddhism holiness.
