Why did Mahavira preach renunciation by fostering a feeling of hatred toward the world and the body?

According to Osho, Mahavira did not teach hatred for the world or body; aversion (dvesha) is only attachment doing a headstand and binds as surely as liking. True renunciation is freedom from both raga and dvesha by shifting from doer to witness. In witnessing, one neither clings nor rejects; one simply sees, and bondage dissolves.
