Study nature, love nature, stay close to nature. It will never fail you.
Look deep into nature, and then you will understand everything better.
The world is big and I want to have a good look at it before it gets dark.
Nature does not hurry, yet everything is accomplished.
In every walk with nature, one receives far more than he seeks.
To walk in nature is to witness a thousand miracles.
The clearest way into the Universe is through a forest wilderness.
