Absolutely. There’s a Catholic priest in India who teaches yoga and find it helps in his vocation. I think yoga can help people develop a deeper and more grounded sense of self, a great foundation for exploring one’s spirituality, whatever the tradition.

I agree with Rik that ...’whatever the tradition’.  I am not Hindu, yet I participate in yoga, I am not Buddhist, yet I kneel in front of monks.  Christian philospohy has some wonderful aspects to it and as yoga is not a religon it would seem that the two would fit like peas in a pod!
