Boastfulness is harmful for life. When somebody develops self-pride, he thinks himself better and more intelligent, and looks down others. As a result, his talents and potentials never develop; but they also tend to be destroyed. So, the self-pride which is harmful for us is good to avoid; moreover, the best creature on this earth as God created us. We are alive because of His grace and mercy. Whatever we do, we do according to His plan and will. He empowers us in everything and makes us successful by giving wisdom. So, there is nothing to be proud, all the glory is for Him. We will listen to a poem in light of it.
