Mangalasasanam refers to a Vaishnava concept in Hinduism, where a devotee offers their salutations and felicitations upon God due to a profound sense of concern for the latter, and also as an exercise of forgetting their sense of self.[1]
See main article: articles, Alvars and Naalayira Divya Prabandham. The concept of mangalasasanam is often associated with the pasurams (verses) of the Alvars, who during the early medieval period of Tamil history (between the 7th and 10th centuries CE), worshipped Vishnu and his avatars through their hymns. This collection of their hymns is known as the Naalayira Divya Prabhandham. The Sri Vaishnava shrines that were extolled by the Alvars are called the Divya Desams, where a number of these poet-saints offered their mangalasasanam.[2]
