Human beings have a drive for security and safety, which is often what fuels the spiritual search. This very drive for security and safety is what causes so much misery and confusion. Freedom is a state of complete and absolute insecurity and not knowing. So, in seeking security and safety, you actually distance yourself from the freedom you want. There is no security in freedom, at least not in the sense that we normally think of security. This is, of course, why it is so free: there's nothing there to grab hold of.
The Unknown is more vast, more open, more peaceful, and more freeing than you ever imagined it would be. If you don't experience it that way, it means you're not resting there; you're still trying to know. That will cause you to suffer because you're choosing security over Freedom. When you rest deeply in the Unknown without trying to escape, your experience becomes very vast. As the experience of the Unknown deepens, your boundaries begin to dissolve. You realize, not just intellectually but on a deep level, that you have no idea who or what you are. A few minutes ago, you knew who you were—you had a history and a personality—but from this place of not knowing, you question all of that.
Liberated people live in the Unknown and understand that the only reason they know what they are is because they rest in the Unknown moment by moment without defining who they are with the mind. You can imagine how easy it is to get caught in the concept of the Unknown and seek that instead of the Truth. If you seek the concept, you'll never be free, but if you stop looking to myths and concepts and become more interested in the Unknown than in what you know, the door will be flung open. Until then, it will remain closed.
I've seen people who have never meditated come to satsang and have a deep experience of the Unknown, and I've known many who remain in the trance because they stay with the mind's techniques and strategies. There is no prerequisite for experiencing the Unknown. Everyone has equal access to it.
