I heard this first from a yoga teacher. In English, we would likely have called it “Advice from a tree” but she is not a native English speaker and she called it a “message” from a tree, which now I like better.
This is what I remember from one reading:
Stand tall
Breathe in the air around you
Love your body
Go out on a limb
Embrace the seasons
Think long term
Don’t forget your roots
Drink lots of water
Enjoy the view
Credit must go to the source — I’m sure my teacher was paraphrasing from Iian Shamir’s “Advice from a Tree” which contains many of these phrases and much more. For me, the simple list above is one that I can remember. That said, I recommend Shamir’s complete poem for its eloquence and the beautiful details woven in, such as the birth of spring and renewal of winter. You can read more about Shamir here.
