You're touching on an important distinction. I listened to an interview with a convert to Catholicism who had practiced Buddhism for a long time and had apparently become pretty advanced according to whatever measure they would use to judge such a thing (sorry, I'm pretty ignorant of the subject so hopefully you get what I mean). Ultimately what caused him to choose Christianity was the realization that the solution to suffering was not to eliminate all desire. It was to embrace desire, realizing that there is a proper object of our hearts' longing and that seeking the right end fulfills our nature and purpose. That said, I do have an appreciation for the notions of sacrifice and discipline and the connection of that to the solution of suffering.
