Question: Can we reduce our need for sleep?

Less than six hours if you get, you will get a headache. But if you become like me, then inside one hour of sleep you can make yourself feel that you have slept for five hours. The clock will say one hour, but your mind and body will say five hours. However, until you have that Yogic capacity, six or seven hours is absolutely necessary for you and others. Four or five hours I don't advise. But if you can't get that six or seven hours at night, then sleep sometime during the day. During your lunch break eat for ten minutes and then, instead of talking with your colleagues, go into your office and sleep for half an hour or forty-five minutes. That will help.
