Sometimes we mistake passion for enthusiasm, thinking that it means we must always keep ourselves busy. But if the mind is not fixed on Krishna in our business, then our activities are simply in the mode of passion, which will lead to suffering. Activities performed in the mode of passion do not satisfy us, nor do they increase our faith in the Lord and His holy name. If we want to actually become enthusiastic, we must understand the purpose behind everything we do; if we are consciously offering our activity to Krishna and we remain steady in the execution of our duties, we will become enthusiastic in whatever we are doing.
