So I realized if they need a shell like that, then clay can be the shell for a ball with many seeds inside. Seed balls need at least one hundred kinds of seeds. One seed eventually makes ten thousand seeds. If you sow seed balls, and wait three years, you will understand what Nature is. It works much better than reading books about Natural Farming.
Seed balls are a small universe in themselves.
I have written six books, but I was unable to express what Nature is in words. So I decided to manifest Nature in form. A seed ball is a one centimeter model of a Natural Farm, with trees, fruits, vegetables and grains. I do not say my one hundred kinds of seeds are the best. It is just an entrance to Natural Farming.
