'Much' of the mind dies upon physical death

[Plenum]

I think the 'mind' that we are capable of 'experiencing' is mediated by the limitations of the physical vehicle of the chosen density.  In our case, that would be a 3d vehicle, with the Veil in place.  

The mind is only really capable of experiencing the 7 rays that each density is subdelineated into.

The thing that underpins and goes beyond all this is the nature of 'Consciousness', which is the universal ingredient, and omnipresent.  We just can't 'see' that it's the one consciousness being experienced in each individuated physical vehicle.

Or think about it this way - because of the influence of the the sex of the physical vehicle (male/female), the archetypal components of mind become much more emphasised depending on if one is biologically male or biologically female.  That 'slant' on the mind is something that is quite a strong influence, and is something that only happens because of the sex of the physical vehicle.  And so even on that level, our 'minds' are being strongly 'influenced'.

The same goes for astrological influences and the insertion of the mind/body/spirit complex into the 3d energetic web.  Those influences upon the experience of consciousness (ie 'mind') are pervasive.
