"You should not do it more than 3 minutes when you are working during the day, or you will become too rich. I am not joking. Doing it for 11 minutes a day is more than enough. Doing it too much will be greed. It stimulates the mind, the moon center, and Jupiter. When Jupiter and the moon come together, there is no way in the world you will not make wealth" - Yogi Bhajan (Jun 21st 1996 )
