I am not convinced that body training will necessarily lead to mindful compassion or ethical living. Mindfulness alone can lead some into a denial of the body and sometimes a complete rejection of the world. Ethics alone can make one self righteous judges over others.

Thus the three provide balance - Heaven and earth meeting within the center (lymbic system) of the body. (There is, however, a fusion of tantien, heart and mind that is very important for manifesting things)

There are many ways to bow and kiss the ground (Rumi). As for me, I follow this 3 fold path. Aikido is a part of that path and helps to inform all three elements.

Namaste,

Chris
