<P> This lesson is recited by religious Hindus, preferably on Tuesdays or Saturdays, these days having been earmarked for special prayers to Hanuman . It happens to be for nullification of the malefic effects of the crow mounted, the son of Surya and Chhaya (Shadow), Lord Shani . Ramayana reveals that Shani Dev, who was captive at Ravana's palace, was rescued by Lord Hanuman . As a token of thanks, Shani Dev offered reprieve to all devotees of Lord Hanuman . Alternately once Shani Dev was caught between Hanuman's shoulders and the ceiling when attempting to mount the latter to influence his stars . Unable to bear the pain, Shani Dev offered gratitude in return to an immediate release . </P> <P> The religious faith suggests that its recital brings harmony to the household . Many Hindus believe that if you do not have time to read the whole Ramayana, you should read the Sundara Kanda . </P> <P> Other versions of the Sundara Kanda exist in other languages as well, for instance in Awadhi, the language in which the saint Tulsidas wrote the Ramacharitamanas . The Sri Ramacharitamanas was written much later than Valmiki's Ramayana, in the 16th century . An earlier Tamil version, Ramavataram, by Kambar is also a prevalent text among the Sri Vaishnava and Smartha Brahmins in South India . </P> <P> M.S. Ramarao wrote Telugu version for Hanuman Chalisa of Tulsidas and Sundara kanda of Valmiki Ramayana as' Sundarakandamu' in Telugu during 1972 - 74 . He sang Sundarakanda in the form of Telugu songs . </P>
