THE NISARGADATTA GITA

 
12. The 'I am' has brought you in, the 'I am' will take you out, the 'I am' is the door, stay at it! It's open!

The feeling 'I am' very clearly qualifies as the port of entry or doorway through which you came into this world and thus it also qualifies as the way out. And there is no other way out! Stay at it and you shall see that this door is always open, it was never closed. Unless you go back and stay in the 'I am' for a sufficiently long time you won't come to know this fact.
