Jiun, a Shingon master, was a well-known Sanskrit scholar of the Tokugawa era. When he was young he used to deliver lectures to his brother students.
His mother heard about this and wrote him a letter:
“Son, I do not think you became a devotee of the Buddha because you desired to turn into a walking dictionary for others. There is no end to information and commentation, glory and honor. I wish you would stop this lecture business. Shut yourself up in a little temple in a remote part of the mountain. Devote your time to meditation and in this way attain true realization.”

I find this an apropos quote for a blog focusing on theory and discussion of physical activities. All of those who write, research, talk, debate and take the academic approach to martial arts need to remember that “the proof is in the pudding”. A building full of people who “talk” are not on the same level of one person who “does”.
