My understanding is quite different:
The first veil that i share with you is understanding that the spirit is physically real and much more information dense than our apparent physical existence. Internalizing this insight is critical to all understanding.
The second veil is to work on ordering your cognitive processes as much as possible to achieve greater access and insight so as to empower your spirit in our physical world. Mathematics helps, but only if you start young and go deep. Otherwise do puzzles.
The third veil is to listen to and to hear the source through the spirits and then be congruent. Disciplined thinking allows you to listen critically and avoid misdirection from evil. Remember all spirits were once human and likely will be human again. The problem is listening to them at all because their own base can be very weak or far worse.
All this is meant to bring you closer to perceiving your spiritual self and to be comfortable. What it is not is a conspiracy theory by usurpers grasping the illusion of power.
