Creative Mind and Success, by Ernest Shurtleff Holmes [1919], at sacred-texts.com
SOME people visualize everything that they think of and many think that it is impossible to make a demonstration unless they possess the power to visualize. This is not the case. While a certain amount of vision is necessary, on the other hand it must be remembered that we are dealing with a power that is like the soil of the ground, which will produce the plant when we plant seed. It does not matter if we have never before seen a plant like the one that is to be made for us. Our thought is the seed and mind is the soil. We are always planting and harvesting. All that we need to do is to plant only that which we want to harvest. This is not difficult to understand. We cannot think poverty and at the same time demonstrate plenty. If a person wants to visualize let him do so, and if he sees himself in full possession of his desire and knows that he is receiving, he will make his demonstration. If, on the other hand, he does not visualize, then let him simply state what he wants and absolutely believe that he has it and the result will always be the same.
Remember that you are always dealing with law and that this is the only way that anything could come into existence. Don't argue over it. That means that you have not as yet become convinced of the truth or you would not argue. Be convinced and rest in peace.
