It's odd to review a book that is both a collection and speeches rendered into text. Given the latter, the "writing" style is casual and less precise than traditionally expected of a formal treatise. But this actually makes his writing more approachable, as the reader doesn't need to pause to try to understand a string of loaded words in run-on sentences as with much philosophy.
The themes in the book are the same as in Freedom from the Known. Krishnamurti is concerned with people being enthralled to their beliefs – including the meaning of past experiences. True freedom, he says, comes daily without regard for the past or planning for the future. Of course, this is inherently impractical in modern society. Even saying I would want to do that, the very wanting is problematic as it entails strife between what is and what could be. Any kind of comparison or desire reveals conflict. "There is fear when there is measurement." Fear is the movement of thought, which must be abandoned. As such, Krishnamurti admonishes the audience simply to be – without consciously relating between subject and object.
While I remain unable to achieve the state of emptiness that enables full attentiveness, reading his words are nevertheless a helpful reminder of how concerned we are with making plans and our worldly affairs. There is good reason for this, of course, and ironically we can plan to just be for a certain amount of time; but our responsibilities to others will eventually come to bear sooner or later. Even thinking about this is what Krishnamurti understands as meditation, rather than how the term is typically bandied as striving for inner peace or oneness or anything at all. Striving is anathema to meditation. Meditation is simply being aware of your thoughts; taking action to remove sources of stress is a bonus, but meditation itself is awareness.
