The mental plane is often depicted as being above the causal plane,but both are really aspects of the same mind.What we call the mental plane is simply the higher aspect of the mind-the region of pure thought-as distinguished from the lower mind which is asocciated with our past and future experiences.Because the mental plane is the highest level of existence concievable to the human mind,it is often regarded as the ultimate spiritual realm and the true home of God.Further studies revealed that the mechanics of creation in our own individual universe are that we,as soul,contact energy fields,or matrices,on the mental plane by directing our attention to them,i.e."thinking" of them.The flow of spirit channeled by Soul`s attention imbues the matrices with additional energy in direct proportion to how long and how intensely we focus on them,regardless of whether the thoughts are positive or negative.Any strongly held thought or belief becomes a dense energy field that attracts more energy,similar to gravity or magnetism.This additional energy is mostly supplied by us and others via imagination and feeling.We "picture" what we`re thinking about,and we attach feelings to our thoughts and beliefs.At that point the energy field grows dense enough to where it becomes visible,or "manifested" on the astral plane.If we continue long enough,and/or intensely enough,to add energy to the matrix with our thoughts and feelings, the energy field`s increased density makes it manifest in our life on the physical plane as matter or action.With the physical plane being the densest state with the highest proportion of matter vs Spirit,it usually takes relativley huge amounts of energy to make a thought or image manifest as physical reality.This inertia is why there is often a lengthy time lag between the inception of a thought and its manifestation in the physical,if it happens at all.Besides inertia,there are any number of reasons why our thoughts and imaginings may never manifest in the physical.Competition from opposing desires of others who share our living space could be one.We exist within a set of agreements we call our family,community,country,planet,and plane,and if what we desires requires a change in one or more of these agreements,manifesting our wants could take more energy than we can muster.Another reason is that we often work at cross-purposes with ourselves.We consciously want one thing and subconsciously something else because of fear or feelings of low self worth,etc.Only when we bring all our energies alignment can manifesting wishes seem effortless.Trying to manifest ideas or desires from the human consciouness can also be frustrating because we don`t always know what all the ramifications of manifesting our desires might be.Instead,we learn to surrender our creative capacity to a higher state that can know all the ramifications,whether we call it our higher self,the Inner Master,Spirit,Divine Guidance,etc.
