The Sacred Fool

Feuerstein equates the Avadhuta with the "sacred fool":

The crazy wisdom message and method are understandably offensive to both the secular and the conventional religious establishments. Hence crazy adepts have generally been suppressed. This was not the case in traditional Tibet and India, where the "holy fool" or "saintly madman" [and madwoman] has long been recognized as a legitimate figure in the compass of spiritual aspiration and realization. In India, the avadhuta is one who, in his [or her] God-intoxication, has "cast off" all concerns and conventional standards.^[4]

I was thinking about Crazy Wisdom practitioners in Christianity. The first and foremost one would be Jesus himself. Tell me that allowing yourself to be crucified and hanging on a cross is not "Crazy Wisdom".

Another example would be Saint Francis who after going into battle as a knight for his city came back with PTSD "Battle fatique". When he recovered enough he walked out on a roof and the birds landed on him because they loved him and his parents and servants were very afraid for his safety as he had been unconscious for so long before he walked out onto the roof to be with the birds.

These are the two very best illustrations of "Crazy Wisdom" in Christianity that I can think of.
