John was suffering from eczema for 23 years. By chanting the Name of
Lord Datta, the eczema began to reduce almost immediately. One of Lord
Datta’s responsibilities in the Universe is alleviating distress
caused due to subtle bodies of ancestors. Within two weeks the hand
was back to a healthy state with no sign of eczema.
