Dikshitar compositions may be described as the products of a mood of contemplation and meditation (dhyana) and reflect the solemnity of the vast inner silence. Behind the marvel of architectural design in sound, there is, in the depth of the songs of Dikshitar, a sense of sublimation, an experience of self-realisation. Every krithi of his may be likened to a Temple, in which the raga installed in the sanctum sanctorum (garbha griha) is situated in the innermost part and is to be reached through the various prakaras.

Namasthe. The article is fantastic. Request you to also enlighten us on vibhakthi krithis of Sri Dikshithar
I visited this great blog while searching for Dikshitar’s Kalavathy Kamalasana yuvathy in Kalavathy raagam. My guru learnt this song from his guru in Benares. But the renditions on the web/ YouTube in raagam yagyapriya are very different. I would like to know the provenance of this song and the original raagam it was composed in. Please do let me know.
Thanks.
Very well written Article. Hopefully this should reach the generations to come.
