I am contemplative by nature, and I've gone to the temple often enough that I know the ceremonial wording and actions pretty well. When I go now, I generally see what hits me as the play progresses and let my mind "wander" a bit to consider whatever hits me. In other words, I spend most of my time there "thinking" - as opposed to "listening" or "understanding".
Perhaps some would say I can do that anywhere, but I don't believe that - for two reasons:
1) It's hard to create a place that is as silent and reverent as the temple - where I can think and ponder without distraction.
2) It's hard to create a place that is as God-focused as the temple - that points my mind to the type of contemplation I do there.
It helps that I view it all symbolically and figuratively - so contemplation becomes the core purpose for me.
