It is commonly accepted that the mind has three divisions: the conscious mind, the subconscious and the superconscious.
There is actually one consciousness.
The subconscious filters the information which passes to the conscious mind in order to protect the conscious mind. The subconscious knows and stores everything that the incarnate human experiences. Our eyes see everything in our field of vision. Our ears hear every sound made in our presence. All that we smell and feel is also recorded. What we consciously notice, however, is up to Personality.
The superconscious mind connects us to each other and to the universal mind.
The mind is housed in the body and trained by the Personality. The mind is influenced by parents, relatives, teachers, friends, enemies, indeed, everyone we come in contact with, especially the "media". This may be beneficial because we are usually born without memory of any other existence and others help us remember what we need to know. There are those, however, particularly the shadow riders, who seek to mislead us and trip us up. And there are those who deliberately use radio, television, movies, the internet and various print media, as well as "entertainment" to cause us to act and react in specific ways, according to their own agendas, which may or may not be in our best interests. This is sometimes called advertising and/or "brain washing".
Personality can chose to listen to the intellect and/or ego, which are both parts of the mind, and/or listen to Soul. The intellect and the ego operate logically, based on what the conscious mind knows. The ego, originally designed to safeguard the mind, unfortunately has been targeted by those whose intentions are not in our best interests. Using the intellect is what is known as left brain processing. Intuitive or right brain processing utilizes the subconscious and the superconscious, as well as direct input from Soul.
Soul is not limited by what the Personality and the mind have learned but it must act through the Personality and the body while in mortal form. Therefore, a major objective of Soul is to become totally one with its incarnate self, the body and Personality it has chosen for this lifetime.
When a person is born, communication between Soul and Personality is unhindered. However, other influences, in time, may result in blocking the Personality from hearing Soul. This may lead to actions by Personality which are in opposition to Soul's purpose.
"Normal" mind chatter interferes with hearing Soul. One way to overcome this is through meditation. Meditation is sometimes described as listening. It is quieting the mind so that the Personality becomes aware and remembers that there is something else besides the mind. When one meditates, one connects with Soul. As this connection is strengthened over time, Soul and Personality become more closely aligned, as Personality chooses to do as Soul wishes. However, complete union takes place only when Personality decides that it wishes to do so. There is no need for Soul to make this decision for Soul loves the Personality and is always in union with it.
The process of Soul and Personality becoming one begins with the Personality's willingness to do as Soul wishes. As the Personality follows the directives of Soul, the bond between Soul and Personality grows stronger. The mind relaxes and is able to safely expand exponentially as Personality consciously controls and changes the way the mind thinks. This results in expanded consciousness and spiritual growth. It may also lead to expanded physical capabilities.
Personality, however, is now not only learning new information and having new experiences, it is also usually unlearning negative habits which may have been acquired along the way. This involves looking at an experience, understanding why it has become part of the Personality, letting go of the emotional attachment and allowing a new pattern of thought and action to takes its place. Sometimes, once a person is aware, this happens easily. Sometimes, it takes a while. Sometimes, the Personality needs to relearn why it has a certain habit or does a certain action which of itself may be "good", but the reason it is done may be fear based. The Personality needs to recognize this and let go of the fear which may be being expressed as anger, hate, anxiety, hostility, etc. For example, one may hold the standard that one does not become romantically involved with a person already in a romantic relationship. However, if this is held out of fear of intimacy, it needs to be relearned. Once the fear is released, the reason for continuing the habit can then become grounded in love.
The process of Soul and Personality uniting as one is a process of letting go of fear and all that is fear based and becoming love. It also allows the Personality access to all the memory and knowledge of the Soul. Soul grows by experiencing. The conscious union of Personality with Soul enables Soul to more fully accomplish Soul's goals and Soul's purpose for incarnating as Personality is more aware of these and acts as a full partner.
