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.
