Nope. The full saying is
"get out of your mind
and into your spirit". You left off the last part "get into your spirit".
It comes from:
Eph 6:18 And
pray in the Spirit on all occasions with all kinds of prayers and requests.
It also comes from the Scripture where it talks about living and walking in the Spirit.
The focus is always about getting into the Spirit, not "out of the mind". In Eastern religions, it is different, their goal is to get out of their mind to escape reality, pain, suffering etc. Our goal is to enter into the reality of Christ by getting into the Spirit. Big difference.
There is little support for "Satan himself operating through Peter". This view makes Peter, a genuine believer basically into another Judas!
Barnes' Notes on the Bible says:
Get thee behind me, Satan - The word "Satan" literally means "an adversary," or one who opposes us in the accomplishment of our designs.
It is applied to the devil commonly, as the opposer or adversary of man; but there is no evidence that the Lord Jesus meant to apply this term to Peter, as signifying that he was Satan or the devil, or that he used the term in anger. He may have used it in the general sense which the word bore as an adversary or opposer; and the meaning may be, that such sentiments as Peter expressed then were opposed to him and his plans.

There is a big difference between the Eastern religion "empty the mind" in silent meditation. Clearly if we are functioning in the meetings (singing, speaking, talking, moving) our mind cannot be empty.
Lee does not teach anywhere to "empty the mind". You would not be able to provide any such quote from Lee.
Instead, Lee taught about the mind/soul being subdued by the Spirit and the mind being changed by the Spirit. For example, he wrote a book "THE RULING OF THE SPIRIT OVER THE MIND". He did not write a book "HOW TO EMPTY THE MIND".
You should review Lee's teachings before posting, it would save you some embarrassment as you appear to be an opinionated person without much facts to support what you write.
