I enjoy reading Osho’s books, even though they do get repetitive (for a good reason), here are some thoughts about them.
Freedom. This book introduced me to a few interesting concepts: “freedom for”, and “three dimensions of freedom”. Given that for Osho (and I agree with him) freedom is the ultimate goal, the topic of freedom is a very important topic. Surprisingly I was thinking very little about this topic before (yet another stab into self-hypocrisy). Great read.
Joy. Yet, another good read. If you understand the difference between pleasure, happiness, and joy, there is no need to read the book. If you do not know what is the opposite of joy, or how pain and pleasure are connected, then, please, read the book.
Intuition. Taxonomy of bases for our actions: instinct, intellect, and intuition. The differences and similarities between these methods are explained. A very good book to read for a scientist.
Meditation. Different meditation techniques with some explanation of why and how they work. An amusing read, but I am not sure that it is fully applicable to our times.
