According to Osho, he favors the West because it lays the scientific, material foundation—the temple’s base—without which spirituality is impotent. He criticizes Indian culture for despising science, preaching escapism and fatalism, and dreaming of a spire with no structure, which bred weakness and slavery. His call is for synthesis: first science (body and power), then true spirituality (the pinnacle).
Build the house first (science and strength), then add the golden roof (spirituality); India skipped the building, the West started it, and both must be joined.
