Seeing the increasingly terror-stricken existential crisis overcoming the faces of many students, realizing that the unbelievable statement of their professor was actually not false, caused many of them to have a mental breakdown. This only made the professor frown even more, as even the best of the best in the next generation were actually so fickle-minded.
But thankfully, there were just as many more among the students who did not give in to their mental instability and analysed themselves in detail, with a cold and calculating calm. That spoke volumes about the extensive knowledge and understanding they had about themselves.
He sighed and decided to continue, not wanting the students to fall deeper into a mental breakdown, since that would actually affect each of their soul sanctums, maybe even cause permanent damage to their souls as Seekers. Since belief and will are the foundation upon which the floors of your sanctum stand, both the primary and secondary aspect chambers.
