29. Last week I asked you to relax, to let go physically. This week, I am going to ask you to let go mentally. If you practiced the exercise given you last week fifteen or twenty minutes a day in accordance with the instructions, you can no doubt relax physically; and anyone who cannot consciously do this quickly and completely is not a master of himself. He has not obtained freedom; he is still a slave to conditions. But I shall assume that you have mastered the exercise and are ready to take the next step, which is mental freedom.
30. This week, after taking your usual position, remove all tension by completely relaxing, then mentally let go of all adverse conditions, such as hatred, anger, worry, jealousy, envy, sorrow, trouble or disappointment of any kind.
31. You may say that you cannot “let go” of these things, but you can; you can do so by mentally determining to do so, by voluntary intention and persistence.
32. The reason that some cannot do this is because they allow themselves to be controlled by the emotions instead of by their intellect. But those who will be guided by the intellect will gain the victory. You will not succeed the first time you try, but practice makes perfect, in this as in everything else, and you must succeed in dismissing, eliminating and completely destroying these negative and destructive thoughts; because they are the seed which is constantly germinating into discordant conditions of every conceivable kind and description.
There is nothing truer than that the quality of thought which we entertain correlates certain externals in the outside world. This is the Law from which there is no escape. And it is this Law, this correlative of the thought with its object, that from time immemorial has led the people to believe in special providence. ~Wilmans~
