Jaimini Sutram translated by Prof. P.S. Sastri:  Preface (page 1.)
NB: There are several translations (versions) of Parasara and, I suspect, Prof. Sastri is quoting from a different one than I have on hand as the chapters he mentions do not correspond to those in my edition of BPHS. None-the-less, the fact that much of Jaimini
has been inserted into BPHS is indisputable.
