Chathussoothri contains the entire message of Brahma Suthras in a synoptic way just as the first four lines of Thiruvoimozhi covering the entire message of Thiruvoimozhi (of Sri Nammaaazwaar).

In the first volume, we present Chathussoothri as covered in Vedantha Saara and Vedantha Deepa, and the second volume contains that’s as presented in Sribhashya.
