Crown Chakra: Spiritual Empowerment.

Affected organs: Spinal cord, brain stem, nervous system. Emotional issues: Spirituality, mental transcendence, connection to the divine.

• General Notes: It is essential to emphasize that traumas in this context are in the mirror of the beholder at the time of the event. Not all maps of chakras are the same, nor are their interpretations entirely uniform.

• Emotional issues: Spirituality, mental transcendence, connection to the divine.
• Possible morbidity: Autoimmune diseases such as MS and ALS. Diseases of the central nervous system. Brain tumors.
• Specific reference: The distinction between chakras 6-7 associated with the brain is particularly delicate; I recommend treating them as one chakra. (even though they are not identical)
• Parallel meridian: There is no parallel meridian to this. Several meridians surround the head itself.

Blockages in several chakras at the same time are common.

The seven human Chakras (Energy Centers) and organs represent respective influential emotions.
