Osho is good for emptying your mind & letting go.
At some point you'd want to find meaning, for which I generally didn't find Osho super useful. I personally found whichever religion you were raised with (or appeals to you most) is the best way to handle this, as it contains answers to many of life & human nature's challenges, which tend to be cyclical over thousands of years.
Other decent reads are the stoics (Aurelius, Epictetus) who teach you how to cope with reality.
Ultimately, these books exist to help you do the inner work to make yourself someone who can handle and thrive through adversity.
