Unfortunately it has elements that are in opposition to the Teachings of The Catholic Church. You will find out why if you will read the articles by Fr. Pacwa and others that I alluded to.
Well, sure, the Spirituality of Yoga does not match all the teachings of the Catholic Church. I am not saying to accept it wholesale, so to speak.
But Yoga can be utilized in Christian Spirituality, for sure. For example, Karma Yoga is simply to offer all one's work to the Lord in a Sacrificial manner. That is biblical.
Japa Yoga is to continually repeat a sacred phrase or Name of God in a prayerful way, which matches the practice of repeating the Jesus Prayer in the Eastern Church, and also praying the Rosary.
Jnana Yoga may be more difficult to find a match for in the Catholic Church. It is related to knowledge of God, for example, through meditation; meditative and contemplative prayer in the Catholic Church, particularly in Monasteries, may be the closest example.
The Spirituality of Yoga is something we can learn from. The key is to practice discrimination. Appropriate what is useful and disregard what is not useful. Many Church Father's appropriated certain truths in Pagan religions.
I think St Augustin said that all truth can be appropriated into Christianity, no matter where it comes from. Those who lack Spiritual Discrimination, however, should stay away from the teachings of other religions. But other religions are not to be rejected in a wholesale fashion.
