Osho on happiness

One thing is certain: you can never become anything other than yourself, and unless you become yourself you cannot be happy. (“The Man Who Loved Seagulls” by Osho)

How true and how hard to achieve. How can we become ourselves if we have really no idea about what we are ?

For me the practices (Reiki, Sun Touch massage, Osho dynamic meditations) are this instrument that makes me myself. And I certainly become happier through the years.
