Question

How can a man spend a month without sleep??

Answer 1

Having meditation throughout the month , he can do this.

Answer 2

Unless that person has sleep disorders, or insomnia, it is almost impossible to spend a month without sleep, because waiting for such a long time without sleeping, is literally not possible for humans. The man will drift off to sleep, without his own knowledge. You can't deny what the sub conscious mind does, it will put the person to sleep.
