“People are constantly crossing over the threshold of Eternity. The door is open if you can stay Awake.” 
What does Rumi mean by “Awake”?
Surely not the first and most familiar dictionary definition; “to cease to sleep; to come out of sleep.”
No, it’s too obvious. There’s another; “to be roused from a state of inaction; to become active.”
If the “rouser” is us, it seems feasible that this inaction could mean sleep or lethargy. That’s normal. We also know what it is like to “awaken” from these states and, by comparison we become active. However, since Rumi wasn’t talking about our normal awake state, could this definition hint at something deeper? If so, who could this rouser be? And what is this state of inaction from which we are to be roused? And into what activity are we to be roused? Maybe we should look deeper.
Actually, there is a further definition; “to be invigorated with new life; as, the mind awakes from its stupidity; he Awoke to life’s higher significance.”
Ah, with this deeper definition, could the implication be that the active wakefulness, of which we are normally aware, is merely an idiotic stupor from which it is not only possible to be roused, but to be invigorated into new life? In the Greek language, the word for “Truth” is alethia, meaning “out of lethargy” suggesting there is no Truth to the stupor at all. If so, it certainly suggests that this new life has nothing to do with our normal “awake” state whatsoever.
It turns out that simply by Recognizing the stupor, We Awaken from it, because We, the Eternal Awakened Self, Is the only One who can Recognize it.
The door to Eternity is open, if you can stay Awake!
