The state of being a Magus is described in Crowley's "Liber B vel Magi". Elsewhere, he admits the possibility of someone reaching this rank without uttering a new magick Word. Such a Magus, he says, would identify himself or herself with the Word of the current Aeon and work to establish it. In "Magick Without Tears", Crowley suggests (without actually saying so) that the Secret Chiefs of the A∴A∴ have reached at least the rank of Magus, in some sense.
