“When Lord Shri Krishna was in Dvaraka, He offered His respects by bowing down at the lotus feet of Narada. When Sudama Vipra came to His house, Lord Krishna personally washed his feet and gave him a seat on His personal bed. Although He is the Supreme Personality of Godhead, Lord Shri Krishna offered His respects to Maharaja Yudhishthira and Kunti. The Lord’s exemplary behavior is to teach us.” (Shrila Prabhupada, Shrimad Bhagavatam, 4.21.38)
