According to Osho, heaven and hell are not locations in the cosmos but psychological states. Hell is the mind in turmoil—neurotic, split, meaningless, dark—self-created chaos. Heaven are brief, cooling moments of relaxation, love, friendship, beauty, and sensitivity to existence. Religions mislabel them as places to exploit fear and hope; real transformation is inner, by changing your consciousness here and now.
Both heaven and hell happen inside your mind—fear and chaos feel like hell; calm, love, and beauty feel like heaven.
