I'm not wild about the notion that becoming a master of ONE type of mysticism automatically makes you an expert at ALL of it. I mean, what would a Tibetan Lamasery teach you about plant magic? These are BUDDHISTS we're talking about here - their whole belief system is about perfecting the self (a vast oversimplification, I know, but still). What would they know about fertility rites? It doesn't make much sense to me.
