Many certified yoga institutes across the world train you in the process, but eventually, it all comes down to you to strive and reach a better state of being through dhyana yoga.
There is nothing like staying in the present moment and being completely aware of it. Many of our problems arise because we get bothered and bogged down by our past or over thinking about what might happen in the future. Dhyana yoga is a path that will help you shun the past and enjoy the present. Go ahead and take up this process because it will help better your life.
