It's pretty sad you can't respect this person's privacy.
Instead of demanding answers it's possible to curiously examine where your experiences might be lacking, because then you might figure out where to look.
Many can experience significant stress or trauma naturally leading to heightened physiological and psychological awareness, it's not a stretch to imagine that could give them a better understanding how the self/ego reacts to the world because that is the source of their pain.
This archetype exists many different forms be they drug induced, "enlightenment", kundalini awakening or seen in Buddhist monks, kung fu masters, famous scientists, philosophers, and historical figures.
If you are genuinely curious there is a British Buddhist monk named Ajahn Brahm[1]. He will be able to communicate the ideas in a western style. It just a starting point though as it has to be experienced first hand either with significant life events or through someone who has already experienced it.
