Sudama and Krishna
Sudama, a poor brahman, was known to be a friend of Krishna from childhood. His brahmin wife always pestered him as to why he did not go to Lord Krishna to alleviate his poverty. He was perplexed and pondered over how he could get re-introduced to Krishna, who could help him meet the Lord. He reached the town of Duaraka and stood before the main gate (of the palace of Krishna). Seeing him from a distance, Krishna, the Lord, bowed and leaving his throne came to Sudama. First he circumambulated around Sudama and then touching his feet he embraced him. Washing his feet he took that water and made Sudama sit on the throne. Then Krishna lovingly enquired about his welfare and talked about the time when they were together in the service of the guru (Sandipani). Krishna asked for the rice sent by Sudama's wife and after eating, came out to see off his friend Sudama. Though all the four boons (righteousness,wealth,fulfillment of desire and libereation) were given to Sudama by Krishna, Krishna's humbleness still made him feel totally helpless.

Therefore, this story shows that sudama unlike other human beings who would seek help from humans went to god instead. He took help from Krishna due to his poverty. Due to Sudama's devotional worship to god, Krishna showed utter humility to him and served him. Although, he is god, the almighty, he still showed so much humbleness and LOVE which us humans don't have and believe we are superior to others. This is the amount of humbleness one has to have to merge with God. This is also shows how humble Sudhama is because he gave up his ego and put all his reliance on God
