A core component of spiritual growth lies in removing all of the thought patterns that we have picked up when we were young. These were just programmed into us. When we learn to remove and reinstall different thoughts and beliefs is when we start to come into our true autonomy as masters over our minds.
And this is partially why meditation is recommended across times and cultures. We are able to calmly observe our own thoughts patterns without reaction or involvement. This is one of the only ways that we can see things objectively. Otherwise, we tend to identify with our gender, political ideologies, nationality, or class. And we naturally see this as ‘correct’ due to our limited life experience.
People who do not understand the power of their own minds are largely lost as they cannot identify as conscious creators of their own reality. They will consistently find fault with the world and ask why it is so difficult to contend with. Understanding the power of thoughts is the first step to personal mastery.
