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.
A sapling must be hedged about for protection, but when it becomes a tree, a hedge would be a hindrance. So there is no need to criticise and condemn the old forms.

A wild boar was sharpening his tusks upon the trunk of a tree in the forest when a fox came by and asked, Why are you doing that, pray? The huntsmen are not out today and there are no other dangers at hand that I can see. True, my friend, replied the Boar, but the instant my life is in danger, I shall need to use my tusks. There will be no time to sharpen them then.
How do the stems connect to the roots?' 'Where is the mist coming from?' 'Why does one tree seem darker than another?' These questions are implicitly asked and answered in the process of sketching.
