According to Osho, people think so differently because thinking is borrowed from the outside—upbringing, education, culture, and countless unique experiences—so no two individuals share the same conditioning; even twins diverge through tiny life events. Hence each person is a conflicting “crowd” of thoughts. Only in meditation, when thinking subsides into silence, do differences dissolve, revealing a shared, nonsectarian human ground.
We think differently because we were taught and experienced different things; when we quiet the mind in meditation, those differences fade.
