Who are Aghoris?
The Aghori are a small group of ascetic Shaiva sadhus who mostly are found in northen India. That means aghori reveres Shiva as the Supreme Being. The Aghoris are one of the principal Indian traditions and the most extreme and fascinating form of the Tantra. They often dwell in charnel grounds, smear cremation ashes on their bodies and use bones from human corpses for crafting skull cups which Shiva and other Hindu deities are often mostly depicted holding or using. Their practices are contradictory to orthodox Hinduism.
Beliefs
Aghoris believe that every person's soul is Shiva but is covered by eight great nooses or bonds, including sensual pleasure, anger, greed, obsession, fear and hatred. The practices of the Aghoris are centered around the removal of these bonds. Sadhana in cremation grounds destroys fear; sexual practices with certain riders and controls help release one from sexual desire; being naked destroys shame. On release from all the eight bonds the soul becomes sadasiva and obtains moksha. So you may have already known being aghoris isn't an easy task.
What do they eat?
Aghori eat every thing from human stool to meat. It is said that they even eat human flesh. But they never kill any creature to eat them they only eat dead rotting animals and humans. For them human meat is not different from any other meat. Aghori smoke marijuana oftenly.
Healing Practice
Aghori practice healing through purification as a pillar of their ritual. Their patients believe the Aghoris are able to transfer health to, and pollution away from patients as a form of transformative healing, due to the believed superior state of body and mind of the Aghori. Aghoris believe that they have a cure to all the ailments and diseases of the humans. They extract special oils from the dead human corpses and make medicines out of them, usually believed to be effective.
Note- Aghoris generally stay away from common people and aghoris are different from fake babas with beard claiming they have achieved enlightment
