Goshin-jutsu

My early martial arts career in NYC was centered around the practice of a modern form of urban self-defense or goshin-jutsu [ 護身術 ] that was derived from Aikidō. Much of my earlier writing as part of the Inner Dharma project was concerned with these arts.

I no longer practice Aikidō, but more recently returned to an examination of the differences between classical and modern approaches to grappling stemming from conversations I have had with exponents of both modern and traditional grappling arts.
