It seems Shingon is one of the more obscure schools of Buddhism, at least in terms of the amount of information available, but after doing some reading about it (namely Taiko Yamasaki's book on the subject) I find that I am very interested in it. Given that information about it is scarce, I am not sure if anyone will be able to answer my questions but here they are:
1. If one desired to become a Shingon monk today, how would they go about doing so?
2. Is there a Shingon monastic community where monks actually live in a monastery today or do the monks support themselves by other means? In other words, how do Shingon monks survive?
3. I've spoken of these concerns before in my initial thread on this forum about the efficacy or potency of particular traditions in the modern era. I know Japan has secularized to a large degree and Buddhism isn't such a huge part of people's lives, so can anyone make any remarks on the state of Shingon Buddhism today, particularly the estoeric practices for monastics?
4. Where would be the best place to go to study Shingon or become a Shingon monk? Obviously Japan comes to mind, but I believed others remarked that there has been a spread of Shingon into Taiwan, and I know there are some Shingon temples in the USA but I am not sure if there is anything like a monastic community or places for serious study.
Those are some of my chief questions as of right now, I'd be greatly obliged if anyone could tackle some of them. If anyone has any remarks, anecdotes, personal experiences, links, or advice regarding Shingon that the feel would be of assistance to me, I'd be happy to hear them.
Thanks in advance.
