Sri Krsna Bhajanmrta - Look! The father is like the guru. His older and younger brothers are also gurus. But the father of one’s father, or a great relative worthy of greater respect, is also guru but his worship should be double that of the father. This is well known among the virtuous people.
-Sri Krsna Bhajanamrta
