Liberation Mutual

On Page  One Hundred and Twenty four (and part of page 123),  Sayadaw tackles the question, If when a person is dying they have strong mindfulness, can they prevent a nimitta of previous unwholesome or wholesome karma from arising?  

It seems like a tedious and only somewhat relevant, and so relevance is what I'm looking for in the answer.

One thing he says is that the yogi could have a stable jahna which can prevent unwholesome signs, and also could have insight-knowledge, the Knowledge of Equanimity Toward Formations, which and produce rebirth as a deva.  As such, all formations will appear clearly in their mind.

He tells the story of three men who were musicians/dancers, and reborn in the deva realm, meeting there a person they danced for when they were in the human realm, who was especially holy.

Sayadaw says that thus, there is no need for life insurance.

Interesting stuff, but hard to prove.  Inspiring but only for a while unless investigated further.
