We must understand that no one is special or greater than other. There were and are so many of us on Earth trying to enlighten others and if we have one affinity or another is just because everyone has an invisible energy that resonates with one or another teacher. To me may be Jesus, to others Buddha or Muhammed or more recent people as Yogananda, it does not matter as long we understand our roles in relation to God. Every single spiritual teacher is trying to awake us, and if the goal is met that is the great achievement. In my humble opinion is very dangerous to argue which one is special or greater. Once we start doing so, we depart the enlightenment path. As a matter of fact we can learn from all spiritual teachers. It is nothing wrong with that, and I think that multi-learning would be our greatest achievement.
