Meditation has been proven to calm the mind, lower anxiety/depression, and even alter our DNA, but it’s hard to master. It can take even a lifetime to master one type of meditation and yet there are many. If you are able to find the type of mediation that suits you best then doing until there is complete mastery of it could take year. Imagine though, if you could simply change your DNA with a simple breath and thought of the mind. This is the kind of thing you want to be able to train your mind to do. When you can do something like that you have trained your mind to the absolute limits of it’s capability.
