I often have people disclose to me that they cannot meditate, because they are unable to clear thoughts from their mind. This is an understandable, but common misconception about meditation.
No one can clear thoughts from their mind. The purpose of our mind is to think; process information, look for threats, etc. It’s what the mind does, it’s what it’s supposed to do!
Think of meditation as a bicep curl for the brain. For example, when practicing “mindfulness” meditation, one focuses on a single point; such as, the nostrils. Focus is directed at the sensation of the air coming in through the nostrils and out of the nostrils.
When your mind wanders, and it will, simply notice it has wandered and bring the focus back to the single point. In doing so, you have just created stronger neural connections in your brain and increased gray matter. This is how meditation is a bicep curl for the brain.
So, each time your mind wanders look at it as an opportunity to strengthen neural connections, increase gray matter creating a healthier brain.
