Sri Karmayogi gave the following as a method to a businessman – (circulated as typed manuscript in late 80’s):

To be free from worry – take a problem or project which is worrying you, first you understand what theoretically the project is, what it practically is. The translation of that project from the paper to the field, what is the mental strength, nervous, physical energy called for by the department or if it is your project, by you. With your experience you would know what is expected of your nerves, of your mind. You first examine whether you have it. The point of exhaustion of skill, capacity etc. is the starting point of worry.

If you don’t have any of it have it, first acquire it before you start implementing any other ideas. If the theoretical basis of a project is fully understood, and its practical necessities are fully conceived, and if they are made fool proof in the consideration, during the course of the consideration, the mind suddenly says, “Yes, I understand all about it. It is not difficult”. The moment the mind gives that unseen signal and there is full understanding of that, the necessary nervous energy comes to us, the mental, nervous, or physical energy needed to put it into practice, comes to us. We live in the moment and all worry goes off.

Once that happens, if you initiate the project now- anything may go wrong, anything may go right, it may be withdrawn, it may be done, everybody may be worried, everybody may panic, but worry cannot enter you. Everybody will be asking you, “Why are you not worried? How is it you are not worried? Do you have an alternative? You’re going to be in soup! The whole scheme has come to ruin. What are you going to do?” It is impossible for you to worry etc., etc.

Once the mind is so fully convinced, what happens, the moment the mental comprehension is complete, it slightly overflows into the next higher level. It begins to have some contact with the next higher level which we call spirit, which one can call the inner being. The strength comes from there and then you feel a relief in the mental consideration of it. The whole thing will go right, it won’t go wrong. Even if it goes wrong, you won’t be worried. Later it will come right. When the mental understanding is just theoretical, paper understanding, mind consents to that 75% or 80%. As long as the mental consent or agreement or understanding is 99%, worry is possible. The moment it is 100%, you turn over in the mind, wait until that signal is given by the mind and a happy relief will be felt.

And then you initiate. Nothing will go wrong. And even if it goes wrong, it will not give you worry.
