A Sage does not belong to this world or to the universe.
Therefore a Sage does not become interested in healing or this would put a Sage on a plane of relativity.
We will not judge who is a Sage or who is not.
But the fact remains in Advaita Vedanta we do not try to heal people.
By your very presence healings may take place, just by being.
This is why it's so important to work on yourself, transcending your body and the world, going beyond health, sickness, wealth, poverty, good, bad, going beyond this duality.
And coming to the place where there is ultimate oneness.
Where you have become pure being.
