So as you know I'm into meditation. There are many different types of meditation but most focus on the same thing which is awakening the Pineal Gland (Third eye). The Pineal gland is a small endocrine gland in the brain.
John Chang has been doing meditation for most of his life. I've seen a lot of people say it's all tricks. I was also a bit sceptical until I started doing meditation myself. I follow Qi-Gong it is a very ancient type of meditation which dates back thousands of years. When I have done these exercises I feel in touch with my spiritual self, I feel tingly sensations in my body and see many different visions in my head.
I have uploaded an E-book which I follow. It is important to read though it first.
I also believe meditation can have a huge effect in bodybuilding. It takes away stress and you have a much better mind-muscle connection.
