Tien,
In: Forums › Questions About Puredhamma Posts › Saddharma Pundarika Sutra (Lotus Sutra) – A Focused Analysis – July 2, 2018 at 9:31 am – I quoted something from the book ‘Theories of Nature and the Universe: Comparison of Pure Buddhist Philosophy’,by Muditha Champika.
What I quoted had to do with the number of ‘world systems’ in ever-increasing coglomerations, closing with ‘up to 1000 x10 ^99 (!!!) world systems, Sata-Sahashri-Loka-datu.’ This is just to indicate the extent of range of it. I have just tried to relocate the book online for you and failed, but the book may well deal with the duration of the various kalpas as well, I do not know. Just something you could look up yourself.
You will please excuse my not contributing to the discussion itself. My concerns have become exclusively the immediate ones.
