According to Osho, the realization of oneness cannot be handed over or borrowed; at best, others may prepare a channel, but relying on a single vehicle is perilous and often fails. Ordinarily, each person must prepare themselves; as much inner capacity as you create, that much grace/energy can flow. Thus, others can realize too—through their own preparation, not by transfer.
Yes, others can awaken to oneness, but each must grow their own readiness—you can’t use someone else’s awakening as a shortcut.
