I am convinced that, if I had not put my coffee habit on hold in the weeks prior, I would have bailed on my ten-day silent retreat. With ten days of quietude, there’s plenty of opportunity to construct a logical argument against staying. For much of the retreat, caffeine withdrawal symptoms would have been sufficient for me to call it quits.
A healthy muladhara asserts our right to exist, to be here. It's name implies it's importance: We need to be able to support ourselves and feel supported. We also need grounding, emotionally through a solid sense of self and physically through our legs. If the root is stable, the other chakras can be stabilized. If there are issues in the foundation, there is almost no hope for the chakras above it.
