knight & yeoman

kill:

What one can do to the body alone - and we are more than flesh and blood.

knot:

"Daddy, will you untie this knot for me?"

Seems a good metaphor for our way through life...

kaleidoscope:

The beauty of the created universe as we spin it in our mind.

key:

Suggests the ability to lock and unlock...a door, an idea, an emotion, a heart. We carry many of them on our key-ring of life.
