Chakras are not points and matters. They related to behaviour, not physical body. They are vital energy and control the emotion.
Chakras include seven majors (Muladhara, Swadhisthana, Manipura, Anahata, Vishuddha, Ajan and Sahasrara).
Muladhara is located at the lower end of the spinal column, corresponds to the sacral plexus. It is pattern and potential energy. Emotion appears when feeling comes with ego and ego comes because of greed and fear, meaning that emotion also appears when feeling comes with greed and fear.
Swadhisthana is located at the genital organs, corresponds to the prostate plexus. It controls the lower abdomen in the physical body.
Manipura, at the navel, corresponds to the solar plexus, includes eyes, sight, planning, fire, money and lampine 4. When energy is converted it will become creativity. Concentration on Manipura removes fear of fire and gives freedom from disease.
Anahata, at the heart, corresponds to the cardiac plexus, means you are affected from outside and inside. For example, when you care for somebody, means that your expectation of what the person is doing something for you or not doing something for you without expectation and thinking but always awearing around. So, do not indulge, repress or suppress. Meditation on Anahata chakra bestows pure qualities, cosmic love and various psychic powers.
Vishuddha, at the throat, corresponds to the laryngeal plexus. It is a sound, needs to speak slowly, emphasize on the tone. Meditation on Vishuddha attains high success, complete knowledge of the four Vedas and knows the past, present and future.
Ajan, between the eyebrows, corresponds to the cavernous plexus. Meditation on Ajan destroys the karma of past lives, and gives liberation and intuitional knowledge.
Sahasrara, at the crown of the head, corresponds to the pineal gland of the physical body. Meditation on Sahasrara attains the superconscious state, the highest knowledge, and become a fully developed jnani.
