There was a wise man living in mountain Wisdom. Tony was one of the
students staying with him. One morning he was teaching about mind
control.
Wise man : “Students, we must control our mind. Think positive and you
will attract positive energy which is good for your mind and health.
Think negative and you will attract negative energy which is bad for
your mind and health.”
Tony : “Teacher, we can think positive, but after a while our mind often
goes blank. We often get sleepy or our mind just wanders somewhere
else. What should we do to make it last?”
Wise man : “When you think positive, how long do you think it can last? Half an hour? Fifteen minutes?”
Tony : “Five minutes, I guess.”
Wise man : “So you do it for five minutes.”
Tony : “That’s it? Only five minutes?”
Wise man : “Yes, then repeat it as many times as you like.”
