What then is being _en rapport_? It is simply an identity of molecular vibration between the astral part of the incarnated sensitive and the astral part of the dis-incarnated personality. The spirit of the sensitive gets "odylised", so to speak, by the aura of the spirit, whether this be hybernating in the earthly region or dreaming in the Devachan; identity of molecular vibration is established, and for a brief space the sensitive becomes the departed personality, and writes in its handwriting, uses its language, and thinks its thoughts. At such times sensitives may believe that those with whom they are for the moment _en rapport_ descend to earth and communicate with them, whereas, in reality, it is merely their own spirits which, being correctly attuned to those others, are for the time blended with them.[50] In a special case under examination, H.P.
