Meditate with no thought of gain.
Expect no ambitions to be fulfilled;
Only then will the inner force manifest.
In the competitive world, we give expression to our ambitions, shrewdness, and aggressiveness. We must do this to survive. In the meditative world, we cannot use these attitudes. What works well on the outside will not serve us on the inside.
When we meditate, we must expect no gain. If we look for results, then those results will elude us. In contrast, if we suspend our ambitions, then the results will manifest very quickly. It may sound like absurd mysticism, but it is an undeniable, empirical truth. If you have no expectations, you will feel the divine. If you strive and have selfish desires, then you will feel only frustration.
When the mind is occupied with meditating for gain, it creates a barrier to precisely the results that you want. Spirituality is a mode that is far beyond the machinations and imaginations of the rational mind. It is created by an aspect of the mind that is not a part of everyday thought. In fact, the part of the mind that brings spirituality is very nearly antithetical to the common ways that we think. Therefore, we can only reach this type of spirituality by suspending our everyday thinking.
