Right from the in-utero stage, we begin to consume millions of bits of information from the world around us, in order to learn its ways and their effect on our survival.
The spoken and unspoken thoughts of people around us; from our parents, family members, relatives, neighbors, friends, teachers to programs on TV and computer, help in programming our sub-conscious mind.
The wave-like electric activity of the brain, which is categorized into 4 main states (depending upon the number of wave-cycles per second), plays a major role in this un-conscious programming.
From womb to the age of two years, the brain operates in Delta brainwave state, the lowest frequency of about 1.5 to 4 wave cycles per second. (At all other ages, this is the operative state of deep, dreamless sleep.)
Anything that is repeated most often and with most intensity is immediately absorbed, and adopted as truth, in this state.
From the ages of two to six, the brain primarily operates in Theta wave state of 4 to 7 wave-cycles per second. (This is the operative state of hypnosis, deep meditation, day-dreaming, or dreaming in sleep. This also occurs during those everyday routine actions that become so automatic that we mentally disengage from them, such as bathing, shaving, brushing teeth etc). This brain state is very receptive to free-flowing ideas in the environment. No wonder children absorb all that they see and hear.
After the age of 6, the brain vacillates between the Alpha state of 7 to 13 wave-cycles per second (a relaxed yet alert state, which is also observed when we are feeling calm, peaceful and meditative. This state is the super-learning state) and Beta state of 13 to 38 wave-cycles (a state ranging from that of regular activity, vigilance, concentration, logical thinking to that of panic, worry and stress reaction.)
Most of our deep subconscious programming happens by the age of 7. However, we continue to be programmed when our brain is operating in Delta, Theta or Alpha states. Under stress, our brain operates from the highest range of Beta state, which is highly resistant to new thoughts and ideas.
(In modern times, television is the biggest programmer of our subconscious beliefs; especially if it is in playing in the bedroom. Pregnant mothers should be very careful of what they think and watch. No one should be sleeping in a room very TV is playing. Children should not be exposed to TV programming. Advertisements on TV affect our psyche more than all other advertisements put together.)
By the age of 7 years the basic foundation of our sub-conscious beliefs is laid. These sub-conscious beliefs attract corresponding experiences in our lives, which further strengthen them. Thus childhood beliefs continue to affect our entire life. About 80% of our thoughts originate from our seven-year-old mindset.
When we come to understand that a lot of the information in our energy field is not really helping us (and perhaps harming us), we can decide to change it; but the new programs can only be installed under right brainwave states.
