There is a story that when the great library of Alexandria was burned, one book was saved. However, it was not a valuable book, and so a poor man, who could read a little, bought it for a few coppers. It was not very interesting, yet there was a most interesting thing in it. It was a thin strip of vellum on which was written the secret of the “touchstone”.
The touchstone was a small pebble that could turn any common metal into pure gold. The writing explained that it was on the shores of the Black Sea lying among thousands and thousands of other pebbles, which looked exactly like it. But the secret was this: the real stone would feel warm, while ordinary pebbles are cold. Therefore, the man sold his few belongings, bought some simple supplies, camped on the seashore, and began testing the pebbles.
This was his plan: he knew that if he picked up ordinary pebbles and threw them down again because they were cold, he might pick up the same pebbles hundreds of times. So when he felt one that was cold he threw it into the sea. He spent a whole day doing this. Then he spent a week, a month, a year, three years… but he did not find the touchstone. Yet he went on and on this way: pick up a pebble, its cold; throw it into the sea… and so on and so on. Just visualize the man doing it for years and years and years — pick up a pebble, it is cold, throw it into the sea… from morning to evening, for years and years.
However, one morning he picked up a pebble, and it was WARM.
Before his senses could have alerted him, he waved his hand and threw it into the sea. He had formed the habit of throwing every pebble into the sea, you understand, and habit made him do it when at last he found the touchstone, poor fellow.
That is how mind functions. Trust is a touchstone. Very rarely do you find a man in whom you can trust. Very rarely do you find a heart that is warm, loving, in whom you can trust. Ordinarily you find pebbles, which look like the touchstone, almost alike, but all are cold. Year in, year out, from the very childhood: you pick up a pebble, you feel it, it is cold, and you throw it into nowhere.
You can apply this learning to any aspect of your life. Be it your friends, relations, your employees, seniors, peers, or for that matter your attendants. Stay cautious so that you identify between cold and warm pebbles !
