The Spiritual Human Anatomy
A human being is a compound of many spirits and sub-spirits.
In total, there are seven main subtleties in the human body which are present in the blood. When enlightened, some of these subtleties are able to produce sub-spirits for a total of 16 spirits that comprise an enlightened human being.
The main souls are: the Qalb (the spiritual heart), the Rouh (the main human soul), the Sirri (the secret), the Khafi (the arcane), the Akhfah (the obscure), the Ana (me) and the Nafs (the Carnal Self). Each of these spirits is related to a particular realm in the universe; when enlightened, they can reach their respective realms through spiritual journey.
'Spirituality has nothing to do with any religion. Spirituality is the knowledge with the help of which you can awaken your souls. You can strengthen them and through them, you reach the higher realms and approach God.'
