This prayer is to destroy evil impartations / spiritual transfers through the laying of hands on you. This could of been through witchcraft laying of hands i.e. fake men and women of God who pose as pastors or prophets of the Almighty God. The teachings starts of by telling you how the enemy can impart evil spirits to you, and one of the ways is by using fake pastors and prophets of God. Making you believe in their ways. This is why you should test every spirit, don't believe in all the miracles you see by these wolves, because the enemy himself is a magician.
These wolves will make you believe that money is deliverance, YOU CANNOT BUY HEALING FROM GOD! YOU CANNOT BUY BLESSINGS FROM GOD! THE MORE MONEY YOU SOW DOES NOT QUALIFY YOU ACCESS TO GOD! ITS YOUR HEART! Acts 8:20 Peter answered 'May your money perish with you, because you thought you can buy the gift of God with money!
You have to be careful who lays hands on your head because your head is a spiritual gateway because when you read Exodus 29:7 it reads "You shall take the anointing oil and pour it on his head and anoint him." The instructions was not hands but head, meaning that through your head spiritually is where the transfer takes place. When baptism takes place, it takes place when your head is dipped in the clean water representing the impartation of the new nature.
If spiritual transfers are done like this believe the enemy will also use that technique to do it too, and it would be through fake pastors/prophets. This prayer is specific and straight to the point after the biblical teachings, because the word of God is a sword that delivers you to the truth and whilst readings deliverance takes place, because evil spirits can not be in the place of truth (your body).
