Jayapataka Swami: So we pray to the Lord that we render pure devotional service, that is not offensive. If we say we are fallen and we want to reach the perfectional stage, that is not offensive. If we want some material benefit by chanting, it is like a business, it is offensive. But if a Santana(child) approaches the parents, they want some help, or maybe that is not the same as approaching and saying they want to serve, but the parents are happy that they are approaching at least for some reason.
