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. 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.
When you rest deeply in the Unknown without trying to escape, your experience becomes very vast. The Unknown is more vast, more open, more peaceful, and more freeing than you ever imagined it would be.
