"Contrary to centrifugal explosion, implosion works inwards, towards the center, centripetally. It concentrates the power towards the center where it... becomes... strongest. ...In the water, the wind, in the sap... and in the blood... movement ...take[s] ...an implosive [course] ...concentrating itself at the center. Bodies of water left to flow naturally turn within themselves, make winding movements that breathe and shelter life. They... regenerate waste water... and... revitalize it. And in the whirlwind... spiral motion is present with a vacuum and low temperatures in the inmost core. The same system is seen in... the universe as spiral nebula. Schauberger recognized this principle while observing in water."
