Mastery of the Mind-Brain Body System in a Mature Way

In another situation, we may actually need to restore and replenish our internal organs. To do that, we can't be in a sympathetic nervous system activation. We actually need to go into more of a parasympathetic mode. So maturity is our ability to use these systems to adapt to different situations. When we are immature, so when we're very, very young, for example, but also we can be older with more years behind us, still immature.
