David's commentary continued: "That is really the core meaning of today's lesson: a neutral thought is impossible. Thoughts are so powerful that they have immediate consequence to the mind. If you're thinking WITH God, if you're thinking WITH love, with Truth, with Source, you are immediately peaceful and loving. And if you seem to believe in anything else, any other thought at all, you are immediately in conflict - there's a war in the mind. Again, this is not a real war because God didn't create fear and war and conflict. And yet in awareness there is not a single neutral thought, ever. So this gives new meaning to Jesus' teaching in the text that you are much too tolerant of mind wandering. This gives new meaning - deeper meaning - to Jesus' teaching that an untrained mind can accomplish nothing. This is showing us right here, just on lesson 16, the ABSOLUTE NECESSITY, the IMPORTANCE, the IMPERATIVE NATURE OF mind training. This is why each day, each moment, is to be dedicated to mind training. In the world mind training is unknown; there's reflections when people say, 'I'm going to my yoga class', but even in that they usually think they're training their bodies. To go to tennis instruction or to go to do stretches, weight training, dietary disciplines, marital disciplines (fidelity), disciplines involving time management - all these things can become meaningful only if it is used for MIND TRAINING. Even the last example I gave - time management - if you give time to Jesus, to the Holy Spirit, this beautiful Presence of love will direct time FOR you - ALL of time. If you give time over to Spirit, Spirit will use the concept of time - of moments, of hours, of days, of events - Spirit will use it all, to undo the belief in linear time, and take you in deep to the acceptance of the Atonement, to a still and tranquil and quiet mind that needs do nothing - to a state of mind in which there is no doer, nothing to be done, nothing EVER done: pure stillness, the Kingdom of Heaven. So practice with me today: 'I have no neutral thoughts'."
