Here is a handy little checklist
-Repentance
-Righteousness
-passing of God`s tests (weighing of soul and judging of deeds)
-Glorious death in battle
-belief in Buddha Amitabha (invocation of his name at moment of death)
-gaining the favor of the gods by living righteously (see point 2)
-baptism
-dying in God`s grace
-penance in purgatory
-mummification
-being provisioned with spells and amulets
If you follow this handy list, you will get to spend the afterlife in Paradise, Valhalla, Sukhavati, Elysian Fields, Heaven and the Fields of Earu. Note how since none of these things contradict each other, you can have all 6.
