We are all snakes. We have a tail and onetwothree mouths. The middle mouth bites the tail to hold fast to form, to keep the extra blessings from dropping off one end and becoming lost in the untidy æther. Leftright mouths are perhaps free to latch onto other snakes should the local geometry and snake density so permit. When our fangs sink into each other we exchange blessings. It must be so. Blessings endlessly recirculated become stale, they need another blood type in which to flow for a time before being returned freshly laundered and creased & giving off a pleasant aroma of incense.
