It is related with Mahatma Gandhi, while he was at Pretoria (South Africa). He was once passing by the house of his good friends, and he thought to make a visit.
It was late in the evening, when he opened the door of the house; he found that the entire family member was at Night Prayer. When the family saw him they welcomed him, of course, and begin to put aside the night prayer, but Gandhiji told them to continue their prayer with these words “Continue with your Prayers”, and said “He to Whom you are Praying/Speaking is Greater than Me.”
