Stainproof Your Mind
Recognizing the power of our minds means that even as unfortunate or terrible things happen to us, we can receive them in a more spacious and ultimately more enlightened way. The Buddha taught his students to develop a power of love so strong that the mind becomes like space that cannot be tainted. If someone throws paint, it is not the air that will change color. Space will not hold the paint; it will not grasp it in any way. Only the walls, the barriers to space, can be affected by the paint.
--Sharon Salzberg, from Lovingkindness (Shambhala)
