Many of us visit family during the holidays. We may look forward to their company -- or dread it. Either way, unless you're Jesus, a fully awakened Buddha, or a zombie (if any of these apply, you can stop reading now), there will likely be some moments when the going gets rough. As a wise teacher (Ram Dass) said, "If you think you're enlightened, go spend a week with your family."
So, what can we do? Unless the situation is so severe that it's best for us to avoid the encounter overall (and this is something only you can answer), you may soon face combustible family moments, even with people you deeply love.
