A narrow vision is divisive, a broad vision expansive. But a divine vision is all-inclusive.
We begin to ask questions, such as: "What is the purpose of life? What is my true nature? What is the source and origin of this entire creation?" When questions of this kind arise in a person's mind, his or her quest for knowledge begins.
When our minds are purified through karma (selfless action) and made single-pointed through up-asana (worship), we cannot remain satisfied with the small achievements in worldly life.
