“The back triangle stance, for instance, in the posture of right hammi, forms a triangle alongside the outside of the right foot with the inside of the left foot. The founder called this stance hito-e-mi. When standing in hito-e-mi, it is possible to execute a strike or thrust without receiving a blow in return.
In Aikido, the second concept, the harmonizing of ki, has many possibilities. In practice, one tries always to blend one's ki with that of the attacker. This enables one to respond in a less severe manner, without thrusting or striking, even when it is possible to do so. Partner blending practices such as kumi-jo and kumi-tachi are done according to basic forms and their purpose is the development of harmony of ki.”
