Islam's founder, Muhammad, used to meditate on a mountain before he claimed the Quran was revealed to him. Buddhism, Hinduism, Jainism, Taoism and many other eastern religions were all founded on meditative insights and meditation is a core practice in these religions. Jesus supposedly lived in isolation for 40 days and after that experienced a transformation. Even Isaac Newton invented Calculus after spending time in exile, because of some pandemic or disease that was spreading at the time he lived.
So clearly meditation, contemplation, introspection, etc. is the basis of all great insights.
