Groundlessness, uncertainty, insecurity, vulnerability — these are words that ordinarily carry a negative connotation. We're generally wary of these feelings and try to elude them in any way possible. But groundlessness isn't something we need to avoid. The same feeling we find so troubling when we open to it can be experienced as a huge relief, as freedom from all restraints. It can be experienced as a mind so unbiased and relaxed that we feel expansive and joyful.
