Variations in the slokam: Kasturi tilakam

While, Kasturi tilakam lalata phalake …. Nasagre nava mouktikam …. being the text of the slokam I found the same slokam with a little variation as sung in Nepal as below: Kasturi tilakam lalata Patale …. Nasagre vara mouktikam Etc etc. Which is the original Sanskrit slokam and why this variation? Kindly enlighten. Thanks.
