I am intrigued with exploring personal training experiences of Fudoshin -- immovable heart, and Suigetsu -- moon on water. These concepts seem very much related to me, although they are different in perspective.
The image of Fudo (Myo-O) holds both a sword -- to cut off fixations of desire, and a rope -- to bind flights of desire. You neither fix on an immediate problem, nor chase things out of reach.
The image of Suigetsu is a reflection of moon in water; no matter how you advance or retreat, it neither recedes nor advances -- perfection in maai: you strike, it dissipates -- and reappears as though never struck.
What personal experiences in training have you had in learning or applying techniques that demonstrated these, or helped you to grasp them ?
I'll chime in with my own if the discussion is of interest.
Cordially,
Erick Mead
