Doi is about being true to yourself. It's about being fearless. It's about being curious about just about everything...about life. If you're a doi, you will stand before a tree and be curious about its life and the life around it and not just congratulate yourself for identifying it and walk away. Doi is being in an eternal state of undisturbed joy.
You're such a doi! It's always fun to be around you.

Be a doi. Don't be so reflective when you're delivering a session.

Derivative of Chinese, doi or doiya. As used in Chinese, doi doi doi. Meaning 'of course, of course, of course.' Translates into English useage as 'Yes, of course,...that's stupid that you didn't know, or that I didn't know it.'
