For instance, the blessing for the body uses the word חלולים / chalulim, “ducts” or “tubes” or “openings.” (In context: “Who formed humans with wisdom and created a system of ducts and conduits within them.”) A chalal is a flute, so this blessing evokes the ways in which our bodies are like flutes through which the ruach ha-kodesh (“holy spirit,” more or less) flows.
“We are all in some way instruments. And we all have to be virtuosos at taking a back seat when necessary. Way back. The prayer life of a flexible instrument cannot be well ordered. It has to be terribly free. And utterly responsive to a darkly, dimly understood command.”
