If we wish to have greater access to understanding, we need to develop our intuition. Intuition can be encouraged through contemplation, periods of silence, and above all a faith in one's self and feelings. It helps if events, situations, feelings, can be visualised. This forms a contact with the visualised object itself and so opens up a channel of relationship to it. Thus, one's intuition is in communication with the event and is able to benefit from a form of direct knowledge with it.
In short, understanding requires developed intuition, which can be encouraged through moments of contemplation and visualisation.
