The Stem of a soul, or rather, one's spiritual Baseline, is the core or root of the spirit. The stem is the inner most component, it is the foundation for a personality, the stem of your inner most thoughts, feelings, perception, love compatibility, emotional stance, and preferences. Its the thing that makes each individual human being different from one and other, regardless of stimuli, environment, mental health, and other surface personality factors. The stem is what causes newborns to have distinct personality traits long before reason, language, and conventional socialization. The spiritual stem, and baseline, is center of one's conscious, subconscious, emoconscious and emosubconscious mind, aswell as the natural reception of the different spiritual stimuli and interpretation of that stimuli through the third eye. In short, it is the foundation or ground layer, of everything pertaining to a human soul.
A spiritual Aura is a still spiritual charge that exists in all living things. the intensity of this charge varies with one's spirituality, spiritual consciousness, natural inclination to a specific charge, and spiritual potential. For example, humans are an interspace above animals, and have soul, and therefore,humans carry a heavier spiritual weight, and as a result, their aura has more potential and flexibility than something without a soul. An aura is the still (very slightly) charged spiritual weight something carries, much of which comes from the spiritual stem.
A spiritual Wavelength is the radius of a being's aura. Aura is closer to water than anything else with respect to its properties so they have the ability to connect with each other. This can result in 'having a bad feeling about someone', or making you feel comfortable with someone else. The average wavelength of a human being (as I've experienced) is typically about 25 feet.
A spiritual Vibration is specific to entities with a soul; when the energy of a soul combines with an aura, it produces a vibration, or rather, the subconscious spiritual movement of energy through an aura. This phenomenon gives life to an aura, and much more tangibility, its like putting electricity (energy) through still water (aura), and using the analogy from my previous example relating to energy, the area of an atom around the nucleus would be the aura, while ofcourse the energy is electrons, and nucleus is the stem. Although vibrations lay dormant when a soul is not engaged in a thought or action that causes the spiritual energy to gain a current charge, or surface charge.
This would be the active positive or negative charge of a soul. The passive charge of a soul is the positive or negative weight of the aura, and activity of spiritual energy in a soul, as separate functions. When the two combine the vibration of a soul re-emerges. Most entities will have an active soul, and so, spiritual vibration most of the time, this is because anything someone does, thinks, or says carries with it a charge, (+), (-), or (N), neutral thoughts are common but pass very quickly, for there is no neutral thought or action that is important to the average human, even mundane tasks typically carry a (+) or (-), for example, feeding your pet is positive, and thinking about a game while someone is talking to you is negative. A vibration has the same wavelength as an aura, but has an intense charge, and also produces a force that can push against the heart and soul.
These five different components of the soul, I believe are not coincidentally a set of five. Five is a very special and sacred number with many meanings and symbolic relevance. A human being in and of its self is made up of five physical components aswell, Head, Right and left arm, and Right and left leg, resulting in an entity that is shaped as a five pointed star. This entity is also comprised of five elements, Water, Earth, Air, Fire, and Mental, with blood containing water, and Fire (plasma), the brain containing the mental element, Air in the lungs, and Earth in the bones (Calcium Carbonate). Also, humans perceive the world through five senses, touch,taste, hearing, sight, and smell. With Five digits coming from each limb, although interestingly, the head has six, two ears, two eyes, a mouth and a nose, with six major parts of the brain as well.
