According to Osho, Western civilization has brilliantly evolved the body (health, work, comfort) and the mind (science, art, aesthetics), but because it stops there, it culminates in a refined sadness and meaninglessness—the feeling of ‘now what?’. Only when the soul is consciously evolved through meditation does this impasse dissolve, flowering into joy, wholeness, and Buddhahood.
If you only grow your body and mind, you end up sad; add soul through meditation to feel complete and joyful.
