SB 5.12.9 — One may say that varieties arise from the planet earth itself. However, although the universe may temporarily appear to be the truth, it ultimately has no real existence. The earth was originally created by a combination of atomic particles, but these particles are impermanent. Actually the atom is not the cause of the universe, although some philosophers think so. It is not a fact that the varieties found in this material world simply result from atomic juxtaposition or combination.
SB 5.12.10 — Since this universe has no real ultimate existence, the things within it — shortness, differences, grossness, skinniness, smallness, bigness, result, cause, living symptoms, and materials — are all imagined. They are all pots made of the same substance, earth, but they are named differently. The differences are characterized by the substance, nature, predisposition, time and activity. You should know that all these are simply mechanical manifestations created by material nature.
