The encyclical letter Laudato Si is available here on the Vatican website. Sobreity is not a switch to turn from off to on. Recovering addicts would tell us the achievement of inner peace is a long pilgrimage.
225. On the other hand, no one can cultivate a sober and satisfying life without being at peace with him or herself.
Some useful reflections on peace:
An adequate understanding of spirituality consists in filling out what we mean by peace, which is much more than the absence of war. Inner peace is closely related to care for ecology and for the common good because, lived out authentically, it is reflected in a balanced lifestyle together with a capacity for wonder which takes us to a deeper understanding of life. Nature is filled with words of love, but how can we listen to them amid constant noise, interminable and nerve-wracking distractions, or the cult of appearances?
For individuals, peace is also not the absence of conflict and inner turmoil.
Many people today sense a profound imbalance which drives them to frenetic activity and makes them feel busy, in a constant hurry which in turn leads them to ride rough-shod over everything around them. This too affects how they treat the environment. An integral ecology includes taking time to recover a serene harmony with creation, reflecting on our lifestyle and our ideals, and contemplating the Creator who lives among us and surrounds us, whose presence “must not be contrived but found, uncovered”.[Evangelii Gaudium 71]
