Dziun, master of Shingon, was a well-known Sanskrit scholar in the Age of the Tokugawa. When he was young, he lectured his fellow students. His mother heard about this and wrote him a letter:
"Son, I think you're a devoted himself to the Buddha, because you want to become a walking encyclopedia for others. No end of facts and comments, glory and honor. I want you to stop these lectures. Take refuge in a small temple in the mountains. Devote their time meditating and in this way Reach true. "
