Ah, now I understand! That is a very wise and insightful quote. It reminds us that how we perceive the world around us is very much determined by our internal state, whether we're calm or agitated, anxious or content. If we can learn to settle our minds and be mindful of our thoughts and emotions, we will see that the external environment can change entirely for us. But if our hearts are unsettled or disturbed by events around us, then just like a chameleon's colors would change alongside its surrounding environment accordingly so would our emotions and moods as per what's happening externally. The key in both situations remains being aware of your inner tranquillity and making attempts to live with equanimity in controllable spaces while managing uncontrollable ones according to its turbulence.
