śrīrājarājeśvarī mantramātṛkāstavaḥ

Sixteen verses to Rajarajeshvari, fifteen of which begin, in order, with the fifteen syllables of the panchadashi mantra, so that the mantra is spelt down the left margin and never stated; a sixteenth closes the set. Every verse ends on the same line, naming her as devoted to the tarpana of the point at the heart of the Shrichakra. The same text stands in this corpus in a longer recension as the Rajarajeshvari Asatvati Stotram, where the acrostic has been broken by an added opening verse — this is the copy in which it still runs clean. The colophon names Shankarananda as its author and styles him the establisher of the Shakta doctrine and foremost teacher of the left-hand observance, which is plainer than such colophons usually are.
