Eastern Meditation mixed with Catholic Contemplation seems to reproduce the heresies of Monophysitism and Monothelitism.
Here are the definitions according to The Modern Catholic Dictionary by Father Hardon. . I’ll let you judge for yourself:
MONOPHYSITISM: A historical system that arose in the fifth century, claiming that in Christ there was only one nature. It came as a reaction to Nestorianism, which postulated two persons in Christ. Among the Monophysites was Eutyches (378-454), head of a monastery near Constantinople. In his effort to save the unity of the Word Incarnate, he suppressed Christ’s human nature. **Other Monyphysites spoke of a single combined nature that was both human and divine. **Condenmed by the Council of Chalcedon in 451, Monophysitism still prevails in the East among the Copts and the Syrian Jacobites (Etym. Greek monos, single + physis, nature.)
MONOTHELITISM: A heresy that began in the Seventh century out of an attempt to conciliate the Monophysites. The latter confused the idea of personality with the undivided activity of a single will, claiming that there was a kind of divine-human operation in Christ. The Monothelites recognized the orthodox doctrine of Christ’s two natures, but taught that these two natures had a common will and a common activity. This view was urged by Sergius (d. 638), Patriarch of Constantinople, who had brought Pope Honorius to support his cause. The East was divided in controversy for over a half century, until the Sixth General Council held at Constantinople condemned Monothelitism in 681. (Etym. Greek* monos*, single + thelein, will.)
My opinion is that if you try to meld Eastern Meditation with Catholic Contemplation, you get a melding (unity, oneness) of human and divine natures and/or a melding (unity, oneness) of Human and Divine Wills, or a combination of one or both. These things appear to fall within the relm of the aforementioned heresies.
Besides … if a Catholic does Eastern Meditation, he’s broken the Second Commandment … possibly a Mortal Sin … and at the least a Venial Sin. Either way, he immediately enters into this type of prayer in a weakened state. Worst case scenario … he’s doing his meditation WITHOUT any Sanctifying Grace, opening himself up to the influences of the Devil without any armor of God’s life. (that’s what happened to me!)
I’ll tell you a personal account. Before I returned to The Church, I was into a lot of “stuff,” one of which was Zen Meditation. I studied and practiced Zen and Buddhism for two weeks, and at the conclusion of those two weeks, I found, through Centering Prayer and Zen Meditation, a dark fiery abyss filled with demons. By the end of the two weeks, I was hallucinating. I saw demons with my waking eyes. I was anxious, stressed out, and on the verge of mental collapse. I was in a state of extreme psychological trauma. I cannot stress enough the extreme danger of Eastern Meditation.
I learned the hard way that Buddhism and the Eastern religions are works of the Devil. God allowed this to happen, in order to teach me this lesson. The “god” of the Buddhists is NOT the Triune God.
True Catholic Contemplation is reserved for FEW souls. It takes obedience to the teachings of the Church Magesterium, conquering of sin through Grace, and often times YEARS of patience and diligence.
Our society is looking for fast solutions to everything. Eastern Mysticism appears to be the fast and easy way to achieve Contemplation. In reality, Centering Prayer is a mirage. If you achieve Nirvana, you will only find darkness and fire.
