Revati can be:: the name of a person ; the wife of Balarama (elder brother of Krishna) ; or a Pisces nakshatra/lunar star ; but for me its Revati ragam in Karnatic music, which is the second ratnangi janya (argh, that is YAB entry sitting as a "draft" since months).

Tala: Adi | Composer: Dayananda Saraswati | Language: Sanskrit.

Arohanam : S R1 M1 P N2 S  || Avarohan  : S N2 P M1 R1 S

where, R1==shuddha rishabham, M1==shuddha madhyamam, and N2==kaishiki nishadham.

Pallavi: bho shambho shiva shambho svayambho
Anupallavi: gangadhara shankara karunakara mamava bhavasagara taraka
Charanam1
: nirguna parabrahma svarupa gamagama bhuta prapanca rahita | nija guhanihita nitanta ananta ananda atishaya akshayalinga ||
Charanam2: dhimita dhimita dhimi dhimikita kitatom tom | tom tarikita tarikitakita tom | matanga munivara vandita isha | sarva digambara veshtitha vesha | Isha sabhesha sarvesha||

So what is it about some ragas that have an attractive quality to them? Apparently listening (and performing?) this raga always evokes deep emotions and feelings. Hmm.... I've heard the same of raga Bhairavi but BHO SHAMBHO in Revati has a very important place for me. I had learnt this raga all by myself more than a decade ago...gee, i wonder how annoyed folks around me would been as i insisted on ghissa'oing the tape 24/7. Nothing else, just one raga months on end and a few months later when I heard CB render it with a plastic bucket as his modified tabla....absolutely mesmerising!! I had to ask him for a jam session and he helped me iron out my rough edges -- He had demoed some swara bhedams and I had no clue that I was making those errors in my niravals. See, now that is the difference between DIY effort and a propah guru to guide ya. Some years later, when I formally learnt it again from a guru, I was able to appreciate the raga more deeply.

Lastly a word on the composer, Dayananda Saraswati. He is the founder of Arya Samaj whose writings, rather commentary on the Vedic/Upanishad texts is very interesting. It has a lot of similarities to Gaudapada's karika on the Mandukya upanishad which inspired the sunyata nyaya. Yet another check in my pending ToReadList.
