I'd like to give a quick introduction on chakras, just a few lines......
Chakras are the energy centers of our body. The traditional "in body" major chakras are seven:
1. Base/First or root chakra, found at the coccyx
2. Second or Sacral chakra, covers the pubic area, uo to about under the navel (more about this later)
3. Third or Solar Plexus chakra (stomach/diaphragm)
4. Fourth or Heart chakra (actually not right on the heart but amid the chest, sternum part)
5. Fifth or Throat chakra
6. Sixth or Third Eye or Brow chakra (forehead)
7. Seventh or Crown chakra (top of the head)
The traditional Sanskrit names are are: (I must admit I never manage to remember them

)
1) Muladhara for the First chakra
2) Svadhisthana for the Second hakra
3) Manipura for the Third chakra
4) Anahata for the Fourth chakra
5) Visuddha for the Fifth chakra
6) Ajna for the Sixth chakra
7) Sahasrara for the Seventh chakra
