Do not let your mind wander..don't empty it either.
I don't care what the guru's say...most of them are just new age "tools" for the evil one.
When our mind is empty or wanders, it is up for grabs.
I personally know that the evil one will feed your imagination and will seize every opportunity to do so.
Can he read your thoughts? No.
But...if you are not in control of your mind or imagination, the evil one will be happy to do it for you.
I made a short recording for you, below.
Love and blessings...Your sister in Christ, Wendy
