The internal revival of the Church cannot be started until Christians radically break with yoga, which is a spiritual opiate for man to make him imperceptive of any spiritual danger (particularly the Oriental and the occult one). When the Lord Jesus cast out the evil spirits, He did not discuss with them.
In exotic wrapping, often disguised as an angel of light, in yoga there comes that serpent of old with an attractive offer: “You shall be as gods...” (cf. Gen 3) The yogi finally believes the devil: “You are god!”
And he begins to consider himself god!
The one who takes yoga courses exposes oneself consciously or unconsciously to demonic powers of hinduism.
