Yoga, before the 1960’s, was practiced by occult practitioners and by the people of pagan religions. Today it has gone mainstream. Yet, the demonic nature of this practice has not changed.
Example – hatha yoga teaches about the way to release a serpent power (Kundalini) through your spinal cord. In the Bible the serpent is associated with satan.
Also yoga is one of the 6 tenets of the hindu religion
Should anyone not wanting to go straight to hell try to garner this serpent (demonic) power?
