For in the true nature of things, if we rightly consider, every green tree is far more glorious than if it were made of gold and silver.
Martin Luther
We've got this gift of love, but love is like a precious plant. You can't just accept it and leave it in the cupboard or just think it's going to get on by itself. You've got to keep watering it. You've got to really look after it and nurture it.
John Lennon
Life and nature are similar concepts because nature is the study of how life acts and interacts within the circle of existence.
