This is from the Yoga Sutras, an old yoga text that consists of threads of wisdom attributed to Patanjali.
What assumptions do you make about other people's intentions? What assumptions might they make about your intentions? What meaning do we make of facial expressions, stray comments, and “out of the blue” laughter?
Often we experience strong emotions and act on assumptions, creating a ricochet effect... and it can be all based on false understanding. We mistake a coiled rope for a snake.
