What motivates you to give? Do you think you have done a good deed and accumulated merits simply by giving? It may not be the case! Your generosity may turn out to be unwholesome. Find out more in the Danavatthu Sutta, wherein the Buddha describes the 8 aspects of giving of which 5 grounds of giving are considered unwholesome and not fruitful and 3 that are wholesome and deserving of merits. So be mindful of your mental states when you next give!
