Pain is what makes us feel alive. When we are happy we get excited and crave for more happiness, in that process we may forget our own existence. Pain is what makes us feel our existence. While growth ,the way our muscles grow while aging and the painful process of bones' growth ,unfortunately we cannot feel most of that pain in our life . Ofcourse hearts are broken while suffering pain, but if we learn to endure pain itself then our hearts will be carved into more beautiful ones.
