Aikido and Zen, five days at Crestone Mountain Zen Center β€” Sept 23–27, with Tres Hofmeister Shihan and Seishin Laurie Nusbaum.

This year's theme is shizentai, the natural body: that balanced uprightness which reveals our inherent capacity for unselfconscious responsiveness. How are the physical and mental postures of shizentai and zazen alike? How do they manifest in our activity?

$395, including lodging and meals. Prior aikido or martial arts experience recommended; meditation experience welcome but not necessary.

Aikido Internal Work,

Power from the Body's Center
In budo, rather than relying on the strength of the arms, one must always draw on power from the body's center.
This is essential because one cannot know the opponent's true strength or ability in advance β€” therefore, it is important to always respond with one's own best power and physical capability.

Aikido Internal Work,

Body gear system
Rather than moving your partner through physical force, what matters most is creating a relationship of unity with your partner β€” one in which, when you move, your partner moves as well.
