The shloka Mangalam Kosalendraya is a prayer seeking auspiciousness and blessings from Lord Rama. The verse praises Lord Rama as the illustrious son of King Dasharatha, the ruler of the Kosala kingdom.
O auspicious ruler of Kosala, repository of the magnificent qualities, the off-spring of the emperor (Dasaratha), the universally & dominant Lord, the erudite expert of the Vedas and Vedanta, the dark-grey cloud-complexioned idol, the exquisitely-attractive amongst men, extolled by virtuous hymns, the eternal Parijata, Sri Rama, the depository of all auspicious qualities, the pleasing personality, the amazing reason for the pleasure on the lotus face of Sita - may he shower prosperity eternally.
