What happens is that they find something.
What they find is a sublime, spiritual peak experience that seems like the greatest experience they have ever had.
But then something else happens. A mistake.
The mistake is that they think having the peak experience is the goal of their spiritual seeking. So they start trying to duplicate it.
When they can’t duplicate it, they experience frustration, unhappiness, and disillusionment. They might even give up on spirituality.
The correction to this mistake is to know that a sublime peak experience is just one possible effect of spiritual seeking.
An effect comes from a cause.
What you should seek is the cause, not the effect.
The cause is aligning yourself with eternal Being.
What you want to duplicate is the cause, cause, cause, over and over. No matter what kind of temporary experience you have.
The cause is the treasure. The effect can end up being a distraction.
The business of spiritual seeking is alignment with eternal Being.
Whatever else happens is just part of the scenery.
