Stig Åvall Severinsen said this quote

If only the physical aspects of hatha yoga are used, it is called ghatastha yoga (ghata means “physical effort”). Modern expressions like “fitness yoga” and “power yoga” that flourish within gym classes are within the same category, even if they do not derive from the original exercises’ rhythm and succession. In many instances “power yoga” has a positive effect on physical health; but if there is no aim to ease the mind, to gain self-insight and control of your thoughts, and to experience the divine within you and within the universe, the deeper meaning of yoga and - possibly life - is lost.

~ Stig Åvall Severinsen

It is impossible to express the experiences you have below the surface with words, when water gently caresses your face and body, the pulse decreases and your brain relaxes. You are immediately cut off from the stress and hustle of everyday life when you are below the surface – there are no noisy telephones or SMS messages, no inboxes full of mail, no electrical bills, or other trivialities of everyday life taking up time and energy. There is nothing connecting you to the surface but the same withheld breath that connects you to life. There is only you and a growing pressure on your chest that feels like a loving hug and the vibrations from the deep quiet tone of the sea. It is quite possible that this deep quiet tone is none other than the mantra Om, the sound of the universe, trickling life into every cell of your body.
