John Erik Hanson:
CHANT "OM MANI PADME HUM" 100,000 TIMES (ABOUT 65 HOURS) AT LEAST 10 MINUTES PER DAY
Hey John,
I hope you're not offended by my funny perceptions, but I read that last part to say "chant for 65 hours at least ten minutes per day" which was pretty amusing

Now that would be some serious practice! I think I'd like to learn how to get 65 hours worth of practice into a 10 minute session.
Anyway, best luck with your practice.
