Gratitude spreads happiness. So open your eyes and look around the richness of creation around you. You are here now today. You are amidst this wondrous display. In silence and grace spend a moment to feel the interconnectedness between yourself and the entire universe. And whenever you experience this grace flow within you, you will find gratitude.
How we interpret information and our experiences of the world depends entirely on how much merit we have accumulated. For example, what does the word impermanent mean? On the grossest possible level, those who have very little merit believe that 'impermanent' means decay and death, or the changing seasons. Once we start to accumulate merit, though, our understanding becomes more subtle. Imagine you are experiencing a moment of happiness. If you have a little merit you will be able, to a certain degree, to interpret and understand 'impermanence' and watch your mood change from unhappiness to happiness and back again, making any disappointment or hope you might feel less intense.
