Delta brain waves are the slowest of all brain waves, ranging from 0.1 – 3.5 Hz. If the frequency of your brainwaves goes any lower, you’ll be brain-dead! Delta is the unconscious level, different from Theta (subconscious mind). It’s also one of the least understood brainwaves, hence not many self-help products focus on delta brainwaves.
Generally people are asleep in delta, when all the other brain waves switch off. It’s a deep, trance-like, non-physical state. People waking up during their delta sleep often feel disorientated and irritable.
Delta is associated with intuition and psychic awareness. In some people, delta brainwaves are present in a waking state, in combination with other brainwaves. These people tend to have strong intuition or psychic abilities.
Delta brainwaves are used as our early warning system to sense when danger is present. It’s a very primal and animalistic brain wave which acts as a kind of “radar”. It enables you to be aware of information that isn’t available on a conscious level.
Delta brain waves are also associated with deep healing of mind and body. It’s been documented that certain frequencies of delta brainwaves stimulate the brain to produce many beneficial substances, including human growth hormone, DHEA and melatonin.
All these substances reverses the effects of aging. At the same time, Delta brainwaves also appear to reduce the production of cortisol (a "stress hormone" which accelerates the aging process).
Anna Wise, in her book "Awakening the Mind – A Guide to Mastering the Power of Your Brain Waves", notes that people in the helping profession often have waking Delta brainwaves. Delta brain waves can also be present in large quantities in hands-on healers --- people who need to reach out and enter into someone else’s mental, psychological and emotional being.
Master Your Mind!
Delta brain waves tap into the external collective unconscious, the universal psyche or mind, beyond our personal self. The collective unconscious is a kind of pool of the cumulative unconscious understanding and knowledge of all humanity. Delta brain waves provide the gateway that links to the collective unconscious and is the source of our intuition.
This is different from Theta brain waves, which provides us insights from our subconscious mind, our inner-most being and inner spirituality. Theta looks inwards and is more personally meaningful to us.
Alpha then brings the messages and insights from Theta and Delta by adding imagery or visualization around the content so that the message can be understood and experienced by the conscious, waking mind. Finally, the message is processed, interpreted and acted upon in Beta, our normal, conscious, waking mind.
As you can obviously see by now, you need to master all four brain wave patterns to master and harness the power of your mind.
