I think in thought systems. I think on a heavenly level. I think on a physical level. Some things exist on both levels. Ideas exist on the heavenly level. Physical level is limited. Heavenly level is limitless. If I give you something physical, I lose that thing. If I share an idea with you, and you embrace the idea, you have all of it, I retain all of it, and so there is only increase, ideas get stronger by sharing, they seem to grow according to Metcalfe's Law. The strength of the idea comes from the number of people who embrace the idea. Ideas can get stronger or weaker with time based on the number of people who embrace it at any given time.
