The tale of human potential

Two days ago I was reading a chapter from Robin Sharma's - "Who will cry, when you die". There he demonstrated the potential of human which is hidden and needs to be discovered. He used a beautiful mythological story to explain this potential and called this as "talent". In a broader meaning, that I perceived from the book : -

"There is a light hidden inside the heart of every human. God didn't hide it in the abyss of ocean because he was afraid someone might go deep into to discover it, he didn't hide it on top of mountain because he knew human potential can drive him to unmatched heights. He decided to hide it inside every human, a place where no one would even think to look. The one who discovers the true meaning of this light lives with a clear aim, the rest die in the pursuit of searching for a greater meaning of his/her life."
