The first energy center is located at the crown of the head, and is accessible from either crown or forehead. This is often depicted as two different centers, but due to their proximity, these are affected as one. To the Egyptians and those that preceded them, this center was known as the Akh. The Akh is the immortal body, that which contains our undying, Essential Selves. This energy center is the point at which the immortal body crosses over with the physical form.

The second center is located at the throat, and is accessible from the mouth or the sides of the throat over the veins. This is known as the Khu.

The third center is located above the heart. This is the Ab. It is accessible directly above the heart, between the breasts. The Ab is the center of the physical being, where the physical stuff of life is circulated throughout the organism. It is a very powerful center of raw life energy. The Ab is the dynamic opposite of the Ba. Where the Ab is the center of the physical life-force, with the heart and all its pumping blood, the Ba is the center of the spiritual life-force and serves much the same function as the heart with circulating and directing the subtle life energies.

The fourth center of power is located in the chest, just beneath the very base of the sternum. This is the Ka. It is here that a strong sensation can be felt during feeding. The Ka is interlinked with the very capacity to feed. It is the seat of the spiritual hunger, as well as the bridge between the subtle energy and the point in the body where this is drawn in and made useful.

The Ba is located in the belly, just beneath the navel. The Ba is the fifth center of the spiritual life force. It sustains the life of the subtle body and connects the subtle body to the physical, transitory form. It is further the tie which connects us to the wheel of death and rebirth. Altering or severing this center completely will affect the way in which the soul travels through the wheel.

Finally, there is a sixth center at the root. This is the Min, the sexual force. This center is most completely tied to the body and is the dynamic opposite of the Khu. This center is accessible through the genitals or just inside the joint of the thigh.
Minor centers exist at the wrists, the insides of the elbows and the backs of the knees. The palms of the hands and the soles of the feet also contain minor chakras. Any of these can be used to create a connection, although we are hardly bound to reach out to another's energy body through these sites. Any physical contact will do, and as mentioned before, even physical contact is not necessary to feed.

One of the must tantilizing elements in Vampire High is the Professor the fact that no one knows anything about him churns ones imagination to try and fathom exactly who is this man,what is he. These questions slowly arise while watching the individual episodes.
Circulation of Energy in our Physical Body

In the body  there are certain centers where energy is concentrated, these energy points are  known as chakras. A connection to a person can be made at any of these centers, bridging the gap between body and energy-body, physical and spiritual. These centers are like bridges between two bodies and one can affect the body on either or both levels simultaneously through the skilled manipulation of these energy centers.

The chakras are like subtle body organs. Each has a different purpose and affect on the subtle and physical form, but for the most part, they all gather, process, and circulate energy. They have been described as "wheels of light", which is indeed the literal translation of the word chakra, and each one has a distinct frequency at which it resonates energy, keeping it constantly spinning, pulsing, and in motion.

The use of these energy centers have been known since the time of ancient Egypt. The energy flowing through these centers is known as prana in Sanskrit. It is chi to the Chinese, ki to the Japanese, the ba or "breath of life" to the Egyptians. The energy has been described as a fluid and has been equated with breath, blood and life by varying cultures. It is the essential stuff of life and yet this fluid, is mutable, and in a constant state of motion. It is the spiritual mercury of the ancient alchemists, the element most crucial to transformation and the creation of the Philosopher's Stone.

Different systems depict these energy centers at varying points in the body. It is usually depicted as  a set of five "wheels of light" which occur in a centralized line throughout the body. These five wheels correspond to five aspects that the Egyptians attributed to the human soul.
