Can I ordain if i have psoriasis? Is one able to be ordained if they have psoriasis? It's similar to eczema but not identical? Will this vary depending on where you go to ordain? Thank you.
It all depends on how severe it is. Two things that are of concern are:

1) Is it visible i.e. on the face or other exposed part of the body such that it puts the faithful followers off?

2) Is it serious such that the itchyness interferes with the cultivation of the practice?

If answers to those two questions are no then there shouldn't be a problem.

I know of a monk who is allergic to wheat and lots who are lacto sensitive.
