[H:O:R:A:C:E]

there's a distinction between the "nature" and the "demeanor" of a person.
to enter the scene through the backdoor would be to approach the situation
according to "nature", where there's no pretenses and the mother figure
would be 'unguarded' or more vulnerable. engaging after exiting through the
front would allow the mother to utilize the bearing she uses to confront the
world at large... rather than to assume that the 'guest' was already trusted.

the whole scene appears to involve your 'higher self' identity arriving at your
location, to access the progress you've made during this lifetime. perhaps the
'special project' for your current self has involved what that poster spoke of.
in general, i see the male energies as representing the spiritual component
of a person, and the female energies as embodiments of the will aspect. for
that man to arrive via the backdoor is an oddity, in that spirit is generally
thought to arrive from "out there" someplace, and not from "within".
