Inner Dharma was a writing project maintained by Mark Raugas between 2004 and 2026 concerned with classical and traditional martial arts and culture. I want to thank all of its readers who provided feedback and encouragement over a period of twenty years. Much of my writing on koryū can now be found in published form as The Truth of the Calm Spirit: The Practice of Shinkage-ryū Heihō as Taoist Internal Alchemy. Some of my work has also been published at Kogen Budo.
