According to Osho, superior bodies alone achieve nothing ultimate; they are refined instruments, not enlightenment itself. Body and soul are two sides of one existence—improving one helps the other, yet awakening is inner. Science should perfect bodily conditions—genetics, prenatal care, health, environment—so higher souls are attracted and supported, while sages and meditation awaken consciousness.
Healthier bodies help, but wisdom comes from waking up inside; build good bodies so wise souls want to come, then help them awaken.
