Nowadays in many places people feed the poor. On the birthdays of saints and Yogis, there is what Vivekananda called seva of daridra narayana.
What is the use of feeding people one day when they have to go without sufficient food all the year round? Those who feed them satisfy their own conscience, I suppose. If you could find out the cause of poverty and try to remove it, that would do some real work.
