There was a Sage called Dattatreya who in the course of his travels at one time was standing near a blacksmith’s shop. A marriage procession with lots of people in their glorious dresses passed by, making plenty of noise. The blacksmith was engaged in making an arrow and did not look up at this procession. Dattatreya was surprised and asked him about the marriage procession. The arrow maker said he was not aware of any such procession and said he was pointing and sharpening an arrow. He was absorbed and united in his work so that the outer world ceased to exist for him at that time. His whole attention was directed to the sharp point of the arrow he was making.
