The brain is a very crafty organ and will do anything to avoid insecurity, suffering and death. It’s number one task is to protect the organism… itself.
For me, Jesus represents truth, wisdom, courage, compassion, justice. And for me a lot of these manifest in his attitude towards death. Which is why he lived so freely.
So of course the mind is going to reject anything that even hints that it must die to itself. It will occupy itself with thinking and fantasies and contemplations to avoid the inevitable call to die.
Understand this and we are on our way to wisdom.
