If you are not capable of helping the poor/miserable who has come to your home then atleast offer him your sympathy, console him and listen to his pain peacefully.
Taken From "Roj Ki Ek Salah" - Book by Acharya Mahashraman
तुम किसी घर आये दीन-दुखी की ज्यादा सहायता करने में यदि समर्थ नहीं हो तो कम से कम उसे अपनी सदभावना सहानुभूती व सान्तवना तो दो, उसका दुःख शान्ति से सुन तो लो.
