world of animals ［畜生界］ ( chikushō-kai): Also, realm of animals or world of animality. The third of the Ten Worlds and one of the three, and the four, evil paths. When viewed as a state of life, the world of animals is a condition governed by instinct, in which one has no sense of reason or morality. Beings or persons in this world stand in fear of the strong but despise and prey upon those weaker than themselves. In The Object of Devotion for Observing the Mind, Nichiren defines the characteristic of this world as “foolishness,” which is one of the three poisons.
