Occultism is a vast and complex subject. It is based on the truth of invisible governing our physical and psychological existence. Science itself has now arrived at some sense of the invisible forces that are behind the observable material phenomenon. This is only the tip of the iceberg.
When it comes to the intricate network of the neurons and the psychological forces the working becomes much more complex and it is not easy to help even when one has discerned the cause. Several factors are involved including the person’s inner state and receptivity.
What one can however do instead is to bypass these forces and invoke the One Divine Power who is the origin and Source of everything and which all the forces ultimately yield to.
My advice therefore would be very simply to place the problem before the Divine Mother and pray. Do it regularly but with faith and without impatience. This way the best possible conditions are created for the best to happen in the play of relativities. For the rest one must trust the Divine Wisdom that works behind everything and uses everything for the ultimate good.
