A day passes, and Buddha Boy shows no signs of dehydration/hydration as predicted by nutritionists. No cracked lips, no yellowed skin. Zilch - he looks completely healthy.
Somewhere after a day, the boy starts sweating profusely. Buddha Boy's teacher is called in to the site close to Buddha Boy. A Buddhist monk of the esoteric Sakyan school, he identifies the yogic method Buddha Boy is using after an hour of meditating in front of him (in some kind of duo meditation) - "tumo"- where the meditator reduces heat loss and maintains a high body temperature. The teacher attempts to "lessen" the "importance" of Buddha Boy by informing the crew that he knows of many lamas in the Himalayas who, like the boy, are doing just such stuff.
