Less is more
In physics, we first learnt about Newtonian physics and later about quantum physics. Sir Isaac Newton was the one who could start to explain the universe with logic. It has become a foundation of our scientific knowledge. Anywhere we are in the world, we have to learn what he explained 300 years ago. One simple principle is about force. If we want move something to move faster, we have to apply more force. By this reason'more is more. That is quite like our life; we learn that to be successful, we have to work hard. Because more study and more work will offer better rewards and consequences. This principle is for the material world.
The mind is not material. It's spiritual. More may not be more when we work with our mind. We better apply quantum physics with our mind training. In the energy world, less can be more. When your mind moves less, when you have less expectation, It will be more powerful.
To meditate is just to do nothing or almost nothing. We listen when people tell us to work smarter, not harder. Meditation can allow us to release that potential which lets us work smarter.
