namah parama-kalyana
namah parama-mangala
vasudevaya santaya
yadunam pataye namah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O supremely auspicious, we offer our respectful obeisances unto You, who are the supreme good. O most famous descendant and controller of the Yadu dynasty, O son of Vasudeva, O most peaceful, let us offer our obeisances unto Your lotus feet.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The word parama-kalyana is significant because Krsna, in any of His incarnations, appears in order to protect the sadhus (paritranaya sadhunam). The sadhus, saintly persons or devotees, are always harassed by nondevotees, and Krsna appears in His incarnations to give them relief. This is His first concern. If we study the history of Krsna’s life, we shall find that for most of His life He predominantly engaged in killing demons one after another.
