After the last trip to Nandi hills,the following passage from Armstrong's book (Its not about the bike) occured to me...
Cycling is so hard, the suffering so intense, that its absolutely cleansing. You can go out there with the weight of the world on your shoulders, and after a six-hour ride at a high pain threshold, you feel at peace. The pain is so deep and strong that a curtain descends over your brain, At least for a while you have a kind of hall pass, and don't have to brood on your problems; you can shut everything out, because the effort and subsequent fatigue are absolute.
