&ldquoThe longer the walk, the deeper the thought&hellip&rdquo An old adivasi proverb I had once heard was taking on new meaning on this hike to Arunachal's Pasang Sonam Tso, near the Tibetan border. Absorbed in &lsquodeep&rsquo thought, I lost my balance and slipped, landing butt-heavy with a comical thud&hellipand I smiled. The fresh moss on the rocks was soft, moist, lush and fragrant. The immediate moment was far more abundant than any profundity of the mind. This trek was anyway about to force some meditation out of me. In the first hour itself, we had already negotiated near-vertical rock patches, with only sparse metal wire to hold on to as placebo, and walked stretch­es on thin bamboo ladders, horizontally placed between cliffs, translucent with dizzying views of brooks far below us. There was little room for thoughts.
