The famous French marine explorer Jacques Cousteau has said: “From the birth, man carries the weight of gravity on his shoulders. He is bolted to earth. But man has only to sink beneath the surface and he is free”. You can experience this ultimate freedom while diving into blue waters of tropical seas or greenish ones of the Arctic seas. Be it warm or icy, crystal-clear or murky, the water above your head obscures the sky, time stops and mundaneness melts away, along with your own body-weight. Silence and serenity surrounds you. Yet you are only a guest in this underwater kingdom, amidst its inhabitants. Do not disturb them, and you may have an amazing experience of being accepted as part of this world for a while.
