If we die to move to 4D, why all the seeming physical preparations?

[Ashim]

Here just a thought.
When you go to 4d for good your 3d physical body ceases to exist. It disapears from a 3rd density perspective. It 'dies'.
This however is not congruent with what many associate emotionaly with death, perhaps as a painful event of losing or damaging the body etc.
When Ra talks about death I feel this may be very open to interpretation as to what exactly is meant.
