Kriya is an ancient science…Elijah, Jesus, Kabir, and other prophets were past masters in the use of Kriya …
ST. PAUL knew Kriya Yoga, or a similar technique, by which he could switch life currents to and from the senses. He was therefore able to say: “I protest by our rejoicing which I have in Christ, I die daily.” By a method of centering inwardly all bodily life force (which ordinarily is directed only outwardly, to the sensory world, thus lending it a seeming validity), St. Paul experienced daily a true yoga union with the “rejoicing” (bliss) of the Christ Consciousness. In that felicitous state he was conscious of being “dead” to or freed from sensory delusions, the world of maya.
