This is the very complex topic what needs a lot of explanation (time and space) in order to be understand properly, as well as good knowledge of English language. Although, I have nothing of that, I still will not be discourage. Consciousness is not one compact whole, but it consists of differences in interaction. Two main opposites are feelings (intensity of consciousness what manifests as unconsciousness) and thoughts or constant activity of consciousness (conscious). Unconsciousness have two opposite impetus what manifest as destructive force or corporal consciousness (subconscious), and creative force what is above conscious or spiritual consciousness. Thoughts are conscious or subjective consciousness what we experience as ego. Subjective consciousness or ego is in constant interaction with objective consciousness or everything outside itself, and in same time with differences inside unconsciousness. For activity of consciousness (thinking) are necessary interaction of differences. Objective consciousness (everything outside of consciousness) activates inside differences with which subjective consciousness (conscious) or ego also have constant interaction. Without differences inside of consciousness we never can feel fight of different wishes, urges or have different thoughts, choices etc. We will not be able to reason, but will react always the same (like robots). In some instances we can react on same way, but that is because, besides inborn corporal and spiritual consciousness we acquire during life half-conscious ego. Half-conscious ego is formed with traumatic experiences when we could not make sense of them. They usually stay as very strong feelings or misinterpretations about us and our surroundings. Those feelings, as new formed, are the closest to conscious, therefore our subjective consciousness first make interaction with them. For corporal and spiritual consciousness need deeper inside interaction. Half-consciousness ego appears as automatic thoughts full of misinterpretations, illusions, prejudices etc.

Although, that consciousness represents instinct of self-preservation it also represents potential self destruction. Base of that destruction is very limited, conditional and pressing development. That development prevents choices. Without choices there is not progress, creativity and continuity. Absence of choices always leads towards destruction.

Above-ego transcendence physical existence and circumstances what are people in. For that consciousness is characteristic constant ability of choices, continuity and development. Motivation of subjective consciousness which choose to develop trough spiritual consciousness is not in separation or individuality, but in synthesis of man with deeper meaning and beauty or perfection of union. Spiritual consciousness is not occupied with bodily needs, but on eternal and beauty beyond body and matter or hidden meaning of essence, not of appearance.
