Why do you refer to such skills as "supernatural" when they are completely natural in the sense of obeying Natural laws.
Also you still haven't shed any light on why anyone who has spent extraordinary effort to actualize non attachment to the very attitudes you expect should motivate them to "come forward", would want to "come forward".
Also why do you require that evidence to convince you should just come along .. but with no corresponding search, effort or personal experience on your part ?
Would that be your expectation for experiencing such things as jumping from an aeroplane or climbing a mountain or diving into a cave or attempting your first ice skating backward somersault, or sitting transfixed during a live performance of Bach's St Mathew's Passion, etc, etc, etc, etc .... .. or facing the physical birth of a child ?
Healthy skepticism is a natural guide for those who are healthy and experienced. Otherwise it's just more armour plating.
