The spiritual world will become revealed only if you demand this revelation through the group during the study. You want to feel the Giver, the Basis, the single Root of everything. However, you should only desire this through the group, through bestowal, according to the law of equivalence of form when you are ready for it.
Even if you still don’t understand what you’re asking for, the Light gradually does its work. When you demand it, the Light acts more and more strongly until the spiritual sensation ignites inside you and becomes clearer.
Then you will see that the spiritual reality exists. The reason for the concealment is the lack of concentration and importance.
