Ajna Charka, the 'command center', corresponds to the cavernous plexus located at the level of the forehead. It has two white petals corresponding to the letters ha and ksha. Its center is of the moon color. It is bright and brilliant from the glory of dhyana, the meditation.
Its associated mantra is OM. It is in relation with:
- Prakriti or the root of all powers of nature in their subtle dimension
- The internal organ or Antahkaran including manas (mental), ahamkara (ego) and buddhi (intelligence)
- The non-breathing
- The cerebellum and the marrow
