All the great teachers of humanity have taught that preliminary purpose of life in their religions. Whatever teachings they have given to their followers, their motive has been to help them to accomplish that first purpose in life. For instance when Christ called the fishermen he said, "Follow me, and I will make you fishers of men." He did not say he would make them more spiritual. That was the first step. He wanted them to accomplish the first purpose of life; the next purpose was to become more spiritual. To the teachers of spiritual knowledge who look at it in this way, their first duty is to show someone how to accomplish the first purpose of life. When they have done this, then they show the second purpose.
