In the Lotus Sutra there are worlds, heavens, purgatories, and so on, making up a very rich imaginary cosmos. Much has been written about Indian and Buddhist cosmology, but none of it is very helpful in facilitating better understanding of the Dharma Flower Sutra. In this Sutra, cosmology is used, not as quasi-scientific description of the universe, but to enhance the place and importance of Shakyamuni Buddha, the Dharma Flower Sutra preached by him, and the world of Shakyamuni Buddha, this “saha world.” It is important to realize from the outset that the cosmological episodes – the mysterious and even magical events that occur in the Dharma Flower Sutra – are imaginative stories, used for the practical purpose of transforming the minds and hearts and lives of the readers or hearers of the Sutra. They are used for the purpose of having us understand – not only in our heads, but also spiritually, in the depths of our beings – that how we live our lives is important, not only for ourselves and those close to us, but for the whole cosmos as well.
