That sounds too bald even for New Age dreamers. Some will have your 'spirit' free-floating in the great cosmic 'out there'. Remove the veil of ignorance. There is a very popular 'Christian' version of this too. Here you even introduce the word 'sin' but limit its meaning and scope.
Sin is defined simply as ignorance, a veil that needs to be lifted in order to uncover the truth.
It is a sort of universalism based on the idea that everyone is essentially good and very much loved by an unconditionally loving God. Sin is being ignorant of these 'facts'. If people would start knowing and believing this, death's sting would become benign, a mere pin-prick. I've attended quite a few funerals over the years. One in particular was noteworthy not because it was different, but because it was so typical.
