The 1,000 names are the traditional Sanskrit stotra (public domain). The English meanings are original summaries written for this edition, informed by the classical commentary of Bhāskararāya; they are not a reproduction of any copyrighted translation.
Devanāgarī and Telugu render Sanskrit fully. Tamil is an approximate transliteration: standard Tamil script cannot distinguish many Sanskrit sounds (for example ka/kha/ga/gha all become க), so Tamil names show the closest available reading using Grantha letters where possible.
