What are Blazon’s standards for sainthood in terms of the "fool-saint" ?

From the text:

“Ah, Ramezay, you are a rash man. Imagine asking a village priest a question like that! But he must have been a fellow of some quality. Not all the Irish are idiots; they have a lot of Spanish blood, you know. That he should know about fool-saints is very odd. But do you know that one is to be canonized quite soon? Bertilla Boscardin, who did wonders—truly wonders—during the First World War with hospital patients; many miracles of healing and heroic courage during air-raids. Still, she was not quite a classic fool-saint; she was active and they are more usually passive—great lovers of God, with that special perception that St. Bonaventura spoke of as beyond the power of even the wisest scholar.”
