They are the regulators, and coordinators of the flow of the various energies, and at the same time act as genuine antennas for the energy exchange between man and the Universe, or between different human beings. The 7 CHAKRA-s are placed outside the physical body, and therefore may be perceived only by clairvoyance, or partly by certain sophisticated hi-tech devices. The 7 CHAKRA-s are, in their order:

1. MULADHARA, at the lowest tip of the spine, and in the area of the perineum; connected with the lowest, and most dense (or "heavy", gross, slow-vibrating) forms of energy, symbolically called the Earth-energy. Related with the vitality of the being, the energy-battery of the human radio-set. Here are the premises of the mysterious energy KUNDALINI, the potential of cosmic fusion.

2. SVADHISHTHANA, three breadths of finger above the root of the penis for men, and clitoris for women; connected with the Water and Moon energies, and the instincts and their accompanying emotions. The mass-consciousness.

3. MANIPURA, at the level of the navel, connected with the Fire, and solar energies, and dynamism, ambition, ego, expansion, will.

4. ANAHATA, in the middle of the chest, corresponding to the Air energies, and to the affective and aesthetic feelings.

5. VISHUDDHA, in the area of the neck, connected with the energy of the Ether (or AKASHA TATTVA), and with the intellectual intuition, and purity.

6. AJNA, in the middle of the forehead, also called the "third eye"; connected with the Macrocosmic mental energies, and the extraordinary capacities of the mind: telepathy, clairvoyance, hypnosis, etc.

7. SAHASRARA, over the top of the head, allowing the opening towards the Supreme Absolute, and granting the condition of wisdom, and Enlightment.

WARMING-UP EXERCISES
It is very important to perform these exercises in the beginning, every time when you attempt to perform the Yogic techniques that are necessary for your Tantra training; this will guard you from any unexpected, and undesirable accidents.

1. The initial awareness
First, let your consciousness take hold of your being. Shift from the street-consciousness, to a calm mood, removing for the period of the training all the unnecessary, secondary, evil, or obsessive thoughts, and replacing them with aspiration, and a positive mood of search of the beneficial, superior, and universally valid accomplishments.

2. Exercise 1
Roll the head very slowly, and amply, both ways, with eyes closed, and attention focused in the area of the throat-CHAKRA. Afterwards note the state of activation of this centre of force, and the mind becoming dynamic.

3. Exercise 2
Perform 5 hasty double-movements of the head: 2 twistings to the left, 2 twistings to the right, 2 bendings half-left, 2 bendings half-right, 2 movements backwards. Keep the attention focused upon the movement, and afterwards try to feel the fine vibrations in the area of the nape, arousing of the latent potential of the mind, and simultaneously the very fine vibrations in the area of the top, arousing of SAHASRARA (the "crown-CHAKRA"), lucidity.

4. Exercise 3
Move the head laterally (to the sides), as ample as possible, keeping the attention focused in the middle of the forehead. Afterwards, note the fine vibrations in this area, arousing of the mental command centre (AJNA CHAKRA), increased mental insight power, as well as free circulation of the energies through the neck, unity between the mind and the rest of the being.

5. Exercise 4
Flex the spine laterally, by moving one shoulder upwards and the other downwards; keep the head and pelvis steady, and focus the attention upon the movement. Note afterwards vibrating points along the spine, deep internal massage, and the healing of the possible sore zones (by focusing your energy upon them).

6. Exercise 5
Stand with feet apart, in angle, and with hands supported firmly on the thighs, as close as possible to the pelvis. The arms shall be perfectly stretched. Exhale through the mouth, inhale through the nose, and remain so, with the lungs filled up, concentrating upon the stream of cosmic energy running downwards through the spine (all the way till the root-CHAKRA). Exhale through the mouth, and relax. Repeat. Afterwards, note "elasticizing" of the spine, "expansion" of the rib-cage, and revitalisation of the entire body, irradiating from the spine.

7. Exercise 6
Massage the spot under the breast-bone with the thumbs of each hand, by turns, as deep as possible; clockwise with the right thumb, and counterclockwise with the left one. Concentrate on the massaged point, and afterwards note the relaxation, energization, and purification in the abdominal area, and the expel of some "toxic" energies at the level of the massaged point.

THE RELAXATION
It is equally important to perform the relaxation every time, in the end of your session of Tantra training. This will guard you from possible disturbances, or accidents.
