Well.. the authors of my book do not make it very clear from where they have
taken the upp part. But they say in their foreward that they used three
books for writing theirs. One is French book by Senart, and two simhalese
translations written by H. Sumagnala and Dhammakriti. I think he got that
part from Simhala books. But again I am not sure. And this book contains
kaccayana vannana in addition to the suttas and vuttis. Anyways.. khalu
akkharvipattiya anattho bhavati. (I think I have written correct pali)
