Then there is another experience. It is not only an experience of spiritual or most advanced people, but it is known even to a scientist, to a material person, to an inventor. He may not believe it, but this experience comes all the same. It is a sense of how to work out his invention, or how to form his system, how to make a plan, or how to arrange something he wants to arrange. One may say that these great inventors have studied mechanics and technique, that it is the outcome of this study that gives them their ability, but there are thousands of students who have studied mechanics and not every one of them is an inventor.
