Yuèshān-guan, alternatively Gassankan [月山館; "Moon Mountain School"] is the name of a private training activity in the Pacific Northwest led by Mark Raugas that is concerned with the development of skill at internal martial arts. I practice Northern Wú (吴) Tàijíquán and related arts as part of Yin Cheng Gong Fa North America.

Inner Dharma was a writing project concerned with classical and traditional martial arts and culture. It resulted in a small book on Jikishinkage-ryū — I want to thank all the readers who provided feedback and encouragement over a period of twenty years.
