Music Tantra/Ragas-Benefits.

Ragas yield various benefits!Most of the time,the names of the ragas suggest what they are capable of yielding.Careful analysis of the formula of the raga(Aarohanam/Avarohanam) also lend deep insight into the raga's tatwa(nature) and its capacity to grant a variety of boons to the practitioner.
Such effects of ragas were well understood and implemented by our saint composers in most of their compositions."Darini thelusukonti,Tripura Sundarini thelusukonti" by Sri Thyagaraja Swami has been composed in the raga SUDDHA SAVERI ("DURGA" in Hindusthani).The Hindusthani name of the raga is a give away of the Goddess forming the raga swaroopa of SUDDHA SAVERI.The fierce and protective Durga is materialised by practising the scale of Suddha Saveri.Sri Thyagaraja himself has conveyed through this raga that the path("Daari") to attain the Goddess is the raga SUDDHA SAVERI.
Similarly,the grand composition of "Devi Brova" in CHINTHAMANI by Sri Syama Sastri is yet another revelation that Kamakshi who resides in "Chintamani Gruha" resides in this krithi too.Tapas or japam (musical term of japam is "sadhana") of this krithi,bestows the grace of Sri Kamakshi.
