Shri Sadguru Sainath says

Unless there is some relationship or connection, nobody goes anywhere. If any men or creatures come to you, do not discourteously drive them away, but receive them well and treat them with due respect. Shri Hari (God) will be certainly pleased if you give water to the thirsty, bread to the hungry, clothes to the naked and your verandah to strangers for sitting and resting. If anybody wants any money from you and you are not inclined to give, do not give, but do not bark at him like a dog."
