He was not speaking for everyone in the world, or his way for all. Those would not be the words of a wise man, but rather of an arrogant man who would wishes to control everyone else. The truly wise are humble and open and are not seeking power and status. There are many good paths to the same goal of Self-Realization/salvation! What may be best for one persons may not be as effective for someone else who can get the same or better results from another approach. However - it may be quite true that there is only one way for you, and only you!
But Yoga Meditation is the great way for those of all paths.
