Namaskaram,
Soubhagya Chintamani is a padhathi which was drawn up by Sage Dhurvasa (Srimad Krodhabhattaraka) which is the text being followed in Kanchi Kamakshi temple. It contains almost all the necessary information to run the temple like Suprabatham time, methods of worship, mantra japa, puja kramam, Diksha niyamam, Utsava niyamam, Utsava kaalams, etc.
Soubhagya Chintamani Kalpa published by Karunanda Mandali, West Mambalam, Chennai has adopted many of these procedures into their puja padhathi. Not only theirs, many Mandali(s) have taken portions of its texts in forming their navavarna puja padhathis.
Thanks
Ram
