Man must also consider, before starting on his journey, whether he has learned all he desired to learn from this world. If there is anything he has not learned, he must finish it before starting the journey. For if he thinks, "I will start the journey, although I had the desire to learn something before starting", in that case he will not be able to reach his goal; that desire to learn something will draw him back. Every desire, every ambition, every aspiration that he has in life must be gratified.
