The Brahma Sutra says: Lushenafo sits in the lotus of Chiba, turning into thousands of Sakyamuni buddhas, each living in the world of Chiba, and the Sakyamuni buddhas in each leaf world turn into billions of Sakyamuni buddhas, sitting on bodhi trees.
Extended information
A flower, a world, a leaf and a bodhi, understanding:
A flower is a universe. A person is also a universe. Everything is small or grand, and the micro world or macro world is one world. For bacteria growing in flowers, where is their earth. Our earth is just a rubber ball to creatures larger than ourselves who grow outside the earth.
When you have the Buddha's nature in your heart, you don't have to dwell on the Buddha's appearance, and you won't see the Buddha by acting in a sensual way. Everything has its own innate Buddha nature, but it is not discovered by itself, and ordinary people do not have the ability to see it. So a tree is also a bodhi.
