Once we are tuned into the basic core of egohood, then anything—any experience, any inspiration—can be made into a further blockage or can become a way of freeing ourselves. Any tendency of mind, even the subtlest suggestion of a tendency, can be viewed with great precision—even something as slight as the irritation from having a fly perched on one’s leg. That irritation might be classified as a friendly one that merely tends to frighten the fly away or an aggressive one that moves to kill it. We can relate to any little irritations like the fly as just the sort of happenings that make up the human situation. We do not particularly make a big deal about it, but we see it precisely.
