“This skill of observation and discernment, which the ancients call ‘vigilance,’ has three elements. First, turn around and meet the afflictive emotion with stillness. Without a dedicated practice this won’t be possible. Second, allow fear to be present. Third, let go of the commentary on the fear. This third element is the most challenging.”
