Dendriform - a lovely word! First it freaked me out and I thought I would really have to cheat but no!
dendriform - adj. Having the characteristic form or structure of a tree
The number one prescription I give all my clients (well all those who live where there are trees, I do have a couple of desert dwellers who can't accomplish this) is to walk in trees, preferably by themselves or with a well-behaved dog. If a person is suffering from depression, from anxiety, from a chronic and persistent feeling of 'not okay' then I suggest walking daily in amongst trees will be helpful. If they are suffering from writers' block, from insufficient love, from too much muchness, or from a sudden attack of the icks - walk amongst trees. And why you may well ask?
When you feel knocked about by life's vicissitudes remember the tree pose in yoga. Let your roots grow long into the earth, reach your arms up to embrace the sky, the light, and just be. You can do it.
