A thought falls onto the soil of the mind. Some bounce off, some lay on the surface. Then some slip in below the surface and start to grow. The best ones are of delightful insight and capture the imagination with new possibilities and realities. Some are just fantasy, but then some contain a real truthful insight and understanding. These are the ones that make life and the experience of life better. Of course other seeds of thought can grow into paranoia and pain. These can be examined to see if they contain some truth to be acted on. Most are just illusions. Trying to pull these weeds only creates resistance and binds the puller to the thought. Try allowing the self to experience the thought, and then let it to evaporate.
