I am not an expert on these types of paradise. I follow the hadiths of Ahlulbayt (a) only when it comes to the descriptions of Heaven. According to our hadiths, it is clear that all levels of heaven are corporeal—they have some sort of physical dimension. Yes, the spiritual reward of God is definitely greater in Heaven, but heaven still has a physical dimension. Some philosophers may have different beliefs, but most Shia scholars have understood that Heaven is definitely corporeal.
