Speaking of vibrational frequency . . .
Electrical activity emanating from the brain is displayed in the form of brainwaves. These brainwave states range from deep dreamless sleep to high mental action. The same four brainwave states are common to the human species. Men, women and children of all ages experience the same characteristic brainwaves. They are consistent across cultures and country boundaries.
There are four categories of these brainwaves, ranging from the most activity to the least activity. You will probably recognize yourself in some of the examples below and how they relate to spiritual awareness. The accepted states of mental consciousness are as follows:
Beta: Alert/Working --- When the brain is aroused and actively engaged in mental activities, it generates beta waves. Beta waves are characteristics of a strongly engaged mind. A person in active conversation would be in beta. A debater would be in high beta. A person making a speech, or a teacher, or a talk show host would all be in beta when they are engaged in their work.
Alpha: Relaxed/Reflecting --- A person who has completed a task and sits down to rest is often in an alpha state. Taking time out to reflect or meditate usually produces alpha waves. When you take a break from a conference and walk in the garden, you would most likely be in an alpha state.
Theta: Drowsy/Daydreaming --- A person who has taken time off from a task and begins to daydream is often in a theta brainwave state. For instance, if you are driving on a highway and discover that you can't recall the last five miles, this is probably theta state--induced by the process of long-distance driving. The repetitious nature of that form of driving compared to a country road would differentiate a theta state and a beta state in order to perform the driving task safely.
Individuals who do a lot of long-distance driving often get good ideas during those periods when they are in theta. People who run outdoors often are in the state of mental relaxation that is slower than alpha and when in theta, they are prone to a flow of ideas. This can also occur in the shower or tub or even while shaving or brushing your hair. It is a state where tasks become so automatic that you can mentally disengage from them. The ideas and thoughts that take place during the theta state are freeflowing and occur without censorship or guilt. This is typically a very positive mental state.
Delta: Sleep/Dreaming --- The final brainwave state is delta. Here the brainwaves are of the greatest amplitude and slowest frequency. Deep dreamless sleep takes you down to the lowest frequency (but never all the way down to zero because that would mean that you were brain dead.
It is a well known fact that humans dream in cycles. When the delta brainwave frequencies increase into the frequency of theta brainwaves, active dreaming takes place and often becomes more experiential to the person. Typically, when this occurs there is rapid eye movement, which is characteristic of active dreaming. This is called REM, and is a well known phenomenon.
Moving through the States of Consciousness
Basically, the four brainwave states of mental consciousness range from the high amplitude, low frequency delta to the low amplitude, high frequency beta.
Research has shown that although one brainwave state may predominate at any given time, depending on the activity level of the individual, the remaining three brain states are present in the mix of brainwaves at all times. In other words, while somebody is an aroused state and exhibiting a beta brainwave pattern, there also exists in that person's brain a component of the other brainwaves.
I believe this is another way spirit contact is facilitated.
When we go to bed and read for a few minutes before attempting sleep, we are likely to be in low beta. When we put the book down, turn off the lights and close our eyes, our brainwaves will descend from beta, to alpha, to theta and finally, when we fall asleep, to delta.
When an individual awakes from a deep sleep in preparation for getting up, their brainwave frequencies will increase through the different specific stages of brainwave activity. That is, they will increase from delta to theta and then to alpha and finally (when the alarm goes off) into beta. If that individual hits the snooze alarm button they will drop in frequency to a non-aroused state, or even into theta, or sometimes fall back to sleep in delta.
During this awakening cycle it is possible for individuals to stay in the theta state for an extended period of say, five to 15 minutes--which would allow them to have a free flow of ideas about yesterday's events or to contemplate the activities of the forthcoming day. This time can be an extremely productive and can be a period of very meaningful and creative mental activity. This is also a GREAT TIME for SPIRIT CONTACT.
Long-time meditators seem to be able to produce a similar experience to the awakening cycle. From my own experience, I would say that it is a weaving together of the various states of consciousness and our mind-body-spirit syncing with the vibrational frequency of those in Spirit that facilitates spirit contact. This can then be verified bythe scientific instruments that measure and quantify brainwaves.
I hope that by recognizing the states of consciousness we can understand our opportunities to connect with Divine consciousness, our spirit loved ones, and our own souls.
