*4 Psychic nerve centers (in Sanskrit – chakras) we only feel these during internalization, under the pressure of concentration; then the energy of the individual chakras can be developed and radiate. Yogis pay attention to the seven primary chakras: 1. Muladhara (root chakra) 2. Svadhishtana (spleen chakra) 3. Manipura (navel chakra) 4. Anahata (heart chakra) 5. Vishuddha (throat chakra) 6. Ajna (brow chakra) 7. Sahasrara (crown chakra).
