Once upon a time there was a fun loving kid who likes to go to beach daily for a walk. One day, while he was playing with sand, found a thing that resembled Shankha. He took it and returned home. Later his father found that the kid has been hiding something and rejected to show it when he asked. The father waited and waited with curiosity thinking that some day the kid will come to him. One fine day he told his father that he found an wounded creature and showed the thing to him. The father told that it was not a creature and not even a living organism. But the Kid didn’t believe his father and kept supporting his argument.
Days, months and years passed. The father passed away and the Kid became a father of two. The children found the Shankha while playing. They took it to their father and asked about it. The Kid (the current father) told like this: “My Children, I found this thing when I was at your age. I kept this along with me all these day. I thought that it was a living creature throughout my childhood. My attachment to this thing grew hard and could not leave it though I knew the reality.” The children satisfied more or less with the answer but felt that it was a precious thing.
Generations passed and the Shankha became their Family Deity. After few generations no one in the family actually knew how they ended up in worshiping the Shankha. All they knew that the Deity protects them from evil and they actually believe.
This is called having faith in something. The faith is driving the mankind. Putting faith in one own self can reach greater heights as the whole world runs on the faith
