The mind is an incredibly powerful instrument. Thoughts, however, at least the kinds of everyday thoughts we have, like “I wonder what I should have for dinner” are mostly obfuscations of reality. One analogy for this is that the mind is as powerful as an elephant, but its being lead around by a monkey, which runs here and there aimlessly. The monkey is our thoughts. When we learn to calm that monkey down by learning to concentrate single-pointedly without the distraction of random thoughts, we can drive the elephant on the path to enlightenment.
