Why do you have to pursue such a difficult, esoteric practice to give full consideration to death? The Ancient Greek philosophers viewed the philosophical life as being, in large part, a preparation for death. For instance, Epicurus had a very clear and simple practice for contemplating & defusing the fear of death. Having spent, probably, the same amount of time reading and "meditating on" Buddhist and Epicurean philosophies of death, the philosophy of Epicurus seems far more simple & effective.
"If death is bad, for whom is it bad? Not for the living, since they’re not dead, and not for the dead, since they don’t exist."
