Inner pleasures.

Since their inner world is so vast, there are souls that almost exert effort to keep it contained. For such individuals, their inner worlds try to seep out and take over the outside world, not the other way around. For them, the external world serves merely as raw material for the inner world—not for processing or utility. These occur within. Because life continues there, like a river flowing beneath the bushes. And since the external world is essentially insignificant to them, these souls can entertain, cheer, or encourage themselves within their inner world in any situation, at any time, and anywhere.
