So I kept her at the assembly on the Spirit Mountain, and gave her the title of Bodhisattva Mahamayuri, Buddha-Mother and Peacock King of Great Illumination.
This is a real deity and not the novel's invention. Mahamayuri, the great peacock, is a protective Bodhisattva of Chinese and Japanese esoteric Buddhism, invoked against poison and snakebite, and 佛母, Buddha-Mother, is a title genuinely given her.
The roc was born of the same mother as she, and so there is some kinship there."
Fifteen characters, and the answer Wukong asked for arrives at last. It is on the mother's side, in the strangest possible sense of mother.
The peacock who ate him is now a Bodhisattva with a title, seated at his own assembly. Attempted murder, an involuntary birth and a mutilation, resolved by promotion.
The title is the real one. Mahamayuri is worshipped across East Asia, usually shown riding a peacock, and her association with the Buddha's mother is part of the tradition rather than a joke the novel is making. The book has taken a piece of actual doctrine and built a family scandal out of it.
And the roc is her brother. Which means the creature that has been eating a kingdom, that outflew the somersault cloud and outthought the Great Sage, is the Buddha's uncle by the reckoning just established — a point Wukong is about to make with great pleasure.
