- Nature has always been and will be always generous of a flawless, endless abundance that never harms. It is enough to know and to conform to its laws to be convinced of it of its rich omnipresent substance of the universe, this source of infinite prosperity which answers all our needs.
- The laws of nature are immutable and eternal. If we know them and live according to her, we will swim in its ocean of abundance. His generosity is second to none. How good it is to live according to nature.
Man will never find an invention more beautiful, simpler or more direct than nature, because in his inventions nothing is lacking and nothing is excessive.
Proverb: by Leonard De Vinci
