Have you ever been really stressed out or felt your life spinning out of control?
Are you ever in a bad mood for no good reason or can you not seem to find the energy to do the things you normally enjoy doing?
Do you think you could be more present in your life or enhance your brains performance relative to your creative or professional output?
While there may be clinical reasons for whatever issue you seek to remedy, it could also be a lack of control over your brains processes and thoughts.
For thousands of years there has existed a mental practice known as meditation which gives the meditator control over their mental processes and lets them fix what ails them or enhance what they already have.
