“The eight stages of yoga include five external preparations and three internal aids to this ascent of the soul, as we would understand it. The two ethical preparatory stages of yoga involve detailed practices of renunciation, restraint from evil and religious observance. The next two steps, the most popularized and emphasized in the West, are physical postures and breath control techniques designed to open, cleanse and fortify variously described physical, emotional, and spiritual aspects of the human person. These aspects are referred to as bodies accessed via the seven chakras (wheels) or psycho-spiritual energy centers located throughout the body. The fifth stage is withdrawal of the senses. The next three stages involve deep concentration, deep meditation and lastly the state of samadhi or self-collectedness, in which the mediator and the object of meditation become one. This is the final stage before union with God or with the Self (as others believe) and the final release from the cycle of rebirth.
At the core of the philosophy of yoga are the beliefs in the law of karma, reincarnation, the potential for self-realization or enlightenment without external aid, and a practiced and finally ultimate withdrawal from the world which is deemed to be an illusion or projection.

Through the Paschal Mystery of His death and resurrection, we and the physical world were redeemed from sin and we were enabled to enter heaven.
** While, doctrinally, yoga is an ancient outdated attempt to attain divine union, practically, this fact means little to a lukewarm laity that is hungry for access to spiritual experiences that they believe (erroneously) their own tradition denies them. Our goal must not only be to point out the hazards of yogic philosophy and practice, but to replace any false concepts and influences by offering seekers the true Living Water that is the gospel and love of Jesus Christ.
Unfortunately, many Christians have experienced some of the beneficial effects of yogic postures, breathing and meditation including extraordinary healing, spiritual renewal and various bliss states. Many have become involved in one of the larger yoga societies or ashrams.”…
