According to accounts of the Buddha's life, it would seem that he had a very deep relationship with nature. He was not born in the royal palace but in a park, under a sala tree. He attained complete enlightenment under the bodhi tree and left this earth to enter Parinirvana, again, between three sala trees. It would seem that the Buddha was very fond of trees.
How often does a man ruin his disciples by remaining always with them! When men are once trained, it is essential that their leader leave them, for without his absence they cannot develop themselves. Plants always remain small under a big tree.
A good civilisation spreads over us freely like a tree, varying and yielding because it is alive. A bad civilisation stands up and sticks out above us like an umbrella-artificial, mathematical in shape; not merely universal, but uniform.
