After death, there are six worlds which we can be reborn in: Hell, Gaki, Chikusho (Animal), Ashura, Human and Heaven, and there is one world in which you can no longer reincarnate – that is, the Buddha World. There are seven worlds to go to after death. Which you choose depends on your life and the level of enlightenment you attained when you were alive. We may advance to the Buddha World, which is the true peaceful place, through our repeated reincarnations. The last teaching to advance to the Buddha World is the Lotus Sutra, which we now believe in. From olden times, the Lotus Sutra has been described as the most difficult teaching to meet and understand, because even to see the Lotus Sutra requires immeasurable years of accumulating merits across many lifetimes.
