piercing concentration

Piercing concentration...yes that is what I would term this feeling of acute focus of body, mind and soul. As I lung forward with each repetitive motion during swimming, all I can see is the forward wall. My mind is numb as though its concentrating deep and hard. The body seems to gyrate with each breath. I can feel pressure on the forehead, right above the center of the eye. It probably is true that Lord Shiva had his third eye loacted at the same spot. Maybe that is the spot where all the forces culminate. I am not a hard core diety prayer conforming type person. But I do pray and most of the time my praying involves meditation. So I conjure up the image of lord Shiva and pray deep and hard. Most Indians don't know that the lingam is actually the male genital of lord Shiva. How ironic is it that a society which is so hush-hush about sexual matters, actually is deeply embedded in sex on a different level like praying to a lingam. I have tried running on thread mills, weight lifting but none of them could bring about so much mind-body awareness as swimming. The body feels fatigued after 15 laps, but the mind remains so elevated as though your day has just begun.
