Q: Is curiosity then an advantage to the spiritual seeker?
A: With humility, it is a useful servant. Without discernment, however, it can lead to serious pitfalls. Curiosity can lead the naïve seeker into blind alleys and useless distractions as well as snares and serious, painful traps. This is where a true teacher is necessary. Again, humility means acceptance of the indisputable fact that cannot be repeated too often: The human mind is incapable of discerning truth from falsehood. Were this not so, there would have been no wars in history, no social problems, and no ignorance or poverty. Everyone would be enlightened, and the consciousness level of mankind would not have remained at 190 century after century.
Curiosity is the aspect of human being. Without it we could be pretty aimless. Most people shoot theirselves and others death by hiding pure Love, Friendship and Peace.
