 Actions motivated by greed, hatred and delusion have a tendency to drive those who do them into the three lower realms of suffering: the hells, the hungry ghost realm, and the animal realm. Actions carried out with better motivations, but still infused with a sense of self, tend to produce rebirth in the three higher realms of titans, humans, and gods. Vast numbers of sentient beings are trapped in this cycle, continually wandering from one realm to another, unable to escape and forced to experience the forms of suffering that exist in each realm. The human realm is particularly fortunate, because it is only in this realm that one can attain Awakening, which liberates one from the whole cycle.
