You can never awaken using the same system that put you to sleep in the first place.
Let us take some event in the life of humanity. For instance, war. There is a war going on at the present moment. What does it signify? It signifies that several millions of sleeping people are trying to destroy several millions of other sleeping people. They would not do this, of course, if they were to wake up. Everything that takes place is owing to this sleep.
Better to die than live in sleep.
