Little dust
"It is related (and the story is no less significant whether historically true or not) that after attaining Enlightenment the Buddha's first impulse was to abide in the effulgence of Bliss without turning back to convey the incommunicable to mankind. Then he reflected, 'Some there are who are clear sighted and do not need my teaching, and some whose eyes are clouded with dust who will not heed it though given, but between these two there are also some with but little dust in their eyes, who can be helped to see; and for the sake of these I will go back among mankind and teach.'" - Arthur Osborne
