SB 10.58.4
yudhisthirasya bhimasya
krtva padabhivandanam
phalgunam parirabhyatha
yamabhyam cabhivanditah
Translation:
After the Lord bowed down at the feet of Yudhisthira and Bhima and firmly embraced Arjuna, He accepted obeisances from the twin brothers, Nakula and Sahadeva.
Purport:
Externally Krsna was the Pandavas’ cousin, and their relationship was just like that between cousin-brothers. Because Yudhisthira and Bhima were externally senior to Krsna, the Lord bowed down at their feet, whereas He embraced His peer Arjuna and accepted obeisances from the younger brothers, Nakula and Sahadeva. Sometimes inexperienced devotees think it is sinful to honor or bow down to an elder brother in Krsna consciousness. But from Lord Krsna’s example here we may conclude that offering all respects to a senior brother in Krsna consciousness is not sinful.
