What was the secret that Faqir Chand realized in Iraq and how does it help explain religious experiences and beliefs other than his own?
When Faqir Chand was in Iraq, he had a vision from a "guru" that told him that the enemy only wanted to collect their dead. he told his officer, and just as he foretold the enemy came to collect their dead. when he returned home, to his suprise he was worshipped as a guru because he appeared to others in visions. Chand however, had no idea that he had appeared to them, and therefore came to the conclusion that visions of gurus were not the gurus appearing to them at all, but in fact a figments of their own imagination.
