Yes it makes perfect sense, thanks for having another stab at explaining it. I think I worry as I have read in several places that the mind and its thoughts at the point of death can determine the realm in which you are re-born. So somebody, even a lama, who had perfectly followed a dharmic path through life may develop dementia and in his last moments be angry with a carer or the world, as his mental faculties have been eroded. However your last post actually reassured me as I think I now understand there is the subtle mind underneath the surface cognitive mind. Thank you! That is something I have been chewing over for a long time and it has gone some way to resolving it for me.
