I know someone who is very frightened about the possibility of life after death, and comforted by thinking of nothingness that he came from before he was born. I've suggested that he try meditating on emptiness. Can anyone provide some links/info about this? He might also be interested in some philosophical info about emptiness, but would rather avoid anything religious.
Have your friend try these. New study suggests meditating on emptiness might be better than mindfulness Meditation On Emptiness Meditations on Emptiness: An Explanation of the Steps For Developing an Understanding That Nothing is Itself
