Life is a never-ending learning process. Whatever happens to us: good, bad, or ugly; it teaches us and cements us for a better tomorrow. Once the learning stops, our will to live starts deteriorating.
Remember all the fights you were part of the college football team, siblings, friends, or ex-lover. They must have taught you one or the other things. You would have gotten things or two from it.
We live in a society, and observing people, animals, and nature can teach us many things. How did our ancestors find what plant is eatable or herbs are good for us, or animals that can be domesticated? Is it not observation?
Where did Yoga come from – Most asanas are animals poses. I will also add that people rejected by society too have something or other to teach us: their fearlessness and breakfree attitude.
That’s how our DNA and brain evolved and made us superior to the rest in the animal kingdom.
