Yoke: The energy that exists between two objects and by attaching to both binds (or yokes) them together. The energy appears in many forms, including in the joints of the horsetail reeds below, in the jugular vein in a person’s neck, and the yoke that fits over an oxen’s neck and allows it to draw a cart (and forces the cart to follow.)

Horsetail Reeds

Little jugulars between earth and sun. They make good whistles, too.
