If you are familiar with "zen" then this book is a pure classic in that genus. To be more precise, this is not even a book in the strictest of senses; perhaps a series of discourse on wide range of topics including self-knowledge, awareness, desire, relationship, time, present-crisis, loneliness, suffering, sex, simplicity, meaning of life, transformation, and so on. Nonetheless, I got bored continuing from this subject matter to that not because the intrinsic contents were less appealing, but because of the fact that things became repetitious. Krishnamurti began by emphasizing on awareness, and then continued on this forever and ever.
Anyway, could there be a solution, "a way out", a remedy to this ever present chaos in this world through any means other than self awareness, by embracing zen, experiencing human life in the "now", from moment to moment, and being so aware that you would not even need a "way out"? I believe, the answer has to be NO. So, if you truly get what Krishnamurti is trying to put out there, you need not even read beyond first few chapters. It is that simple, as the title itself suggests awareness to be the first and the last freedom.
Another thing, Krishnamurti has utterly rubbished out knowledge, philosophy, beliefs, meditation and yoga in the form of escapism, words, language, dogmas (well, I was reminded of those inspirational twaddles you see these days on instagram/facebook quite a lot; though I adore some of them myself and wish them to keep on coming). However, I would like to quote the author on his view of how ego works. (though J Krishnamurti, throughout this book has hit out on words and labeled such quotes as coming out of an uncreative mind). He marked, "If I see the necessity of being clean, it is very simple; I go and wash. But if it is an ideal that I should be clean, then what happens? Cleanliness is then postponed or is superficial."
Although this book has not got much in store for gratification in terms of literary genius, it is one of those books that can change your life views, and give you a completely novel perspective to how you see your life. As many of the remarkable books on zen, this one too does not teach you anything at all, but instead help you unlearn awful lot of things that you have always been carrying heavily with you to little avail. In summary, the author makes a very humble request to just go with the flow, and experiment with being aware from moment to moment without any sense of justification. If you love, you love; if you are happy, you are happy; if you hate, you hate; if you are sad, just be sad, so miserably sad; if you are angry, be a complete anger, in totality, do not condemn, do not resist, but just be aware.
