The faultfinding mentality is described as one of the weaknesses of the heart, hrdaya daurbalya. It is an anartha which obstructs our progress on the path of devotional service. As long as these anarthas are there in the heart, it is very difficult to make progress. The result is that when we are chanting the Holy Name of the Lord, and we are associating with devotees, it is very difficult to experience some taste in Krishna consciousness. Instead of actually relishing the mellows of the Holy Name, we oftentimes will simply look to find fault with others. Alternatively, we might think, “Look at me, look how I am relishing the Holy Name of the Lord.” In other words, we are not really absorbed in the Holy Name—we are simply thinking of how others are perceiving us. So, we need to understand the real source of this faultfinding mentality. If we want to uproot it, we have to be aware of its existence.
