A HOLY WELL AT ARDFERT.
Srimad-Bhagavatam 7.14.25 Translation
During these periods of seasonal change, if one bathes in the Ganges, in the Yamunä or in another sacred place, if one chants, offers fire sacrifices or executes vows, or if one worships the Supreme Lord, the brähmanas, the forefathers, the demigods and the living entities in general, whatever he gives in charity yields a permanently beneficial result.
