The knowledge you are given in initiatic teachings is so far removed from your usual field of awareness that it does not immediately penetrate your brain. But out of everything you have heard or read, something necessarily remains in your subconscious, and one day when your capacity for understanding has developed, this knowledge will come back to you.
If you want to gain a faster understanding of initiatic truths, you should train your brain. It is the finest of instruments. It does not grow weaker with age at the same time as the other organs, because it is where the divine hierarchies have placed their power.
That is, it does not grow weaker, if it is nurtured by mental activity. For what is thought? It is a kind of ladder we have received from Cosmic Intelligence which we must learn to use to go higher.
