Speaking of who Osho was, it pays to do research (I'm aiming at the editorial reviews here, naturally). He didn't flee the US - he got deported on fabricated INS charges, and there were no orgies at Rajneeshpuram. However, libel sticks. This story (a thoroughly fascinating one - how the Reigan administration got so afraid of a little Indian man that they broke a couple dozen of American laws trying to shut him down and force him out) is still awaiting an unbiased teller.
Osho belonged to the venerable tradition that says: human beings are basically consciousness. Everything else, including our bodies, and our lives, is minute circumstance. The only purpose is to help the consciousness become aware of itself (aka enlightenment), the only path there - meditation. Anything else is only used to help the people meditate, as needed. Osho spent the majority of his life promoting the cause, and certainly sacrificed lifetime for it - he died prematurely even considering his rather ill health (he was asthmatic, diabetic, and had back problems, but granted the very high level of care afforded him, the above shouldn't have killed a 59-old man).
For everything else, read the man himself. This lovely book is as good a place to start as any.
LOVE can only happen in FREEDOM, which does not mean 'I do what I want without thinking of what it could mean to you', but, 'I have respect for you just as you are, and, I have a high opinion of what are your needs.'
If you are asking yourself 'do I love myself? do I love my partner?' and the answer is 'yes, but...' then it would be a very good idea to deal with and spend some time on this book.
If I am able to stand my own ALONENESS, I will get to know myself. This coming to knowledge and to experience regarding myself will be of benefit to your fellow human beings and especially to your partner.
LOVE FREEDOM ALONENESS are three aspects that can not be disconnected from eachother. They will toghether create and strengthen a deep and intense connection in your relationship.
The 'true love' people are searching for is possible, indeed, but you have to take the chance to get on this way and you have to be courageous. But it will be worth the effort!
