While the Manasarovar yatra does not involve much trekking, it requires the pilgrims to grapple with low oxygen environments due to high altitude. As the pilgrim is traveling over high terrain, they are likely to experience symptoms and discomfort of altitude sickness (headache, loss of appetite, nausea, exhaustion, sleeplessness, breathlessness etc.) until their body adjusts to the elevation. This can take a couple of days or more depending on the individual. This may exacerbate the health condition for people with pre-existing medical conditions that are unsuited to high altitude environments.
Further, Kailash is an energy powerhouse that, in the consciousness of the Master, will effect powerful spiritual transformation that may manifest as physical symptoms such as pain, body ache, etc. or emotional upheavals. Hence, the participants must ensure that they have the requisite fitness levels and the flexibility and agility to navigate such terrains as also the mental fortitude to deal with the travails of intense spiritual transformation.
Physical fitness plays a key role in adapting to such environments which can be enhanced through regular practice of yoga, pranayama or any other form of physical conditioning.
