The higher self prepares to withdraw and offers its power to the disciple below it, and the disciple asks for the inheritance of the firstborn. The Jordan has already been crossed, meaning the flowing river of ordinary consciousness has been passed over and the 2 now stand on the far ground of a higher state. Elijah is the ascending master principle about to rise out of the body; Elisha is the awakening self that must receive the breath before the elder power departs. The double portion is the firstborn's inheritance, the request to hold not a copy but a fuller measure of the spirit than the one who carried it.
What rises does not simply leave; it hands its breath to what remains, and the seeker asks to inherit that breath in double strength so the work does not die when the master vanishes.
Jordan: the flowing river of ordinary consciousness that must be crossed before a higher state is reached
Spirit: the breath and living force that passes from the ascending self into the one prepared to receive it
