Anyone who has a pure and neutral mind will know when they are going to die and how. When seeing the dead body of themselves, they can use the experience for recollection of death (Marananusati), in our wisdom we see our body and mind as impermanent suffering, and non-self. Somebody ever be able to look into the future during meditation and be able to look back into previous lives. Whenever you see past lives living compound things are subject to change according to the factors of good deeds (caused by merits) or bad deeds (caused by passion or cravings).This will cause a person to be reborn in either a happy or a suffering world. Anyone who is attached to these compound things with cravings and illusions, bad speech, bad action, bad and evil thoughts, will be reborn in a suffering world, while living a meritorious life of good deeds will lead to bliss and happiness in the next existence. The effect of suffering and happiness might even be experienced in the present lifetime. You will finally realize that each life you observe is in fact non-self and no permanent refuge to anyone. You should have a neutral mind that is free from any feeling, happy or unhappy, to obtain a peaceful mind.
