The seventh volume of "Avalokitesvara Bodhisattva Popular Products" by Hokkekyo describes in detail the benefits of Guanyin Bodhisattva to all sentient beings in the world of Nuwa, saying that all sentient beings who suffer are single-minded, and Guanyin Bodhisattva can instantly see their voices and get rid of them. If they want anything, they can also show their Buddha's body, bhikkhu's body, excellent female body and so on.
The basis for men to wear Guanyin and women to wear Buddha;
"Men wear Guanyin and women wear Buddha" is a folk psychological prayer, which has no basis in Buddhist scriptures. "Men wear Guanyin" mainly in ancient times, hoping that men can be less violent and as compassionate and gentle as Guanyin Bodhisattva; And "women wear Buddha" is to hope that women are less jealous and narrow-minded, like Maitreya Bodhisattva, and more tolerant.
In fact, Buddhism has no fixed phase, Buddhism is boundless, and there is no gender difference between Buddha and Bodhisattva. How can men and women wear it?
