If you observe the principle elements of nature, everything in it seems to have two common qualities. One is, if controlled and given to us in the perfect measured doses, it is beneficial to us, so much so that life without it is impossible. And the other is if let go and left wild and untamed they can destroy us violently. The earth itself, where we live, can destroy us with earthquakes or volcanoes. The sun, which gives us daylight, energy, but if too close can burn us. Water, the main element of life, can destroy cities with floods and tsunamis. Winds can offer pleasant breezes, enable pollination and much more, but can destroy us with hurricanes and tornadoes. Fire can provide warmth, light and let us cook, but can burn us too. The same tree that provides cooling shade, can fall on us and kill us. Mountains can provide breathtaking views, but can destroy us with avalanches. Even the changes in climates: Summer is seen as a blessing in some countries, like Canada because of how mild and pleasant it is compared to long and harsh winters. And winter is long awaited and considered a blessing in other countries of the desert, that have endured long and harsh summers. My point here is, there is an ayah in all elements of nature. Allah tells us to observe and reflect on nature, and anyone with intellect will see how it is like a wild beast that has been subdued and humbled for us by Allah. So that perhaps we may be grateful. And so that perhaps we may learn to humble and tame down the storms and urges within our own physical self, and our nafs. We are also after all, made from this same earth.
