A flower-related story

Came across this story some time ago and would like to share
it. When Guru Nanak, the founder of the Sikh faith, visited
Multan then a great religious centre, the fakirs there sent
him a cup of milk full to the brim,suggesting thereby that
the place was already full of holy men and that there was
no place for another one.
The Guru placed a jasmine flower on top of the milk and
returned the cup to the fakirs, thus telling them that as
the flower with its weightlessness floated on the surface
of the milk without displacing it, so would he live in their
midst adding only fragrance with his presence.
