In this particular course at Gracewave Church in San Diego, CA., Dr. Caroline Leaf helps us perform some self “brain surgery without the blood” by bringing toxic thoughts into captivity. Since 1981, she has researched the science of thought as it relates to thinking, learning, renewing the mind, gifting, and potential. Dr. Leaf has an online 21-day brain detox that capitalizes on the fact that every moment of every day you are changing your brain with your thoughts in a positive or negative direction. Every time you think and choose, you cause structural change in your brain. Your thoughts impact your spirit, soul, and body.
