Blown Wide Open is a book that shows you your essential being of freedom. It is not philosophy or a description of freedom; it reveals truth in a clear and obvious way as you are reading. It does not lay out yet another path and another goal, other than recognizing your freedom here and now.
The means Sal uses for this recognition is called HOLIDAYS. As Sal states in the Introduction to Holidays, "A Holiday is being blown wide open, knowing who you are, being who you are. It is both the goal of freedom and the way of liberating your mind from fear, doubt, suffering, delusion and seeking. It is the goal, in that, a Holiday reveals the truth that freedom is your natural human condition, here and now. And it is the way in that, continuing to be on Holiday resolves the tendencies that cause suffering and doubt, and brings an end to seeking anything."
If you are interested in coming to know freedom, yes, it is possible and yes, this book can help you recognize that which is now and always has been true for you.
