Thinking leads to philosophy. It is the dimension of mere thinking. It does not lead to experience. There is a lot of walking in it but one reaches nowhere. There are many conclusions but never the ultimate conclusion that brings the solution in life. This is only natural. Even the most perfect thinking process about water cannot quench one’s smallest thirst. The path to quench one’s thirst is quite different. By thinking you can attain intellectual conclusions, while through meditation you attain spiritual experience. One is like thinking about water; the other, like quenching one’s thirst. One is still part of the problem; the other is the solution.
Lao Tzu asks everyone this question: Do you want to know light or to know about light? Do you want to know truth or do you want to know about truth? Do you want to know about water or do you want to quench your thirst? Your answer to these questions will decide whether you are thirsty for knowing or for collecting information.
