"“I have shown in my books that the ten books of the Rigveda were composed in the following order: 6,3,7,4,2,5,8,9,10 (with parts of book 1 spanning the periods of composition of books 4,2,5,8,9,10); and that they were composed as follows: books 6,3,7 in the Early Rigvedic period, books 4,2 in the Middle Rigvedic period, and books 5,1,8,9,10 in the Late Rigvedic period (the hymns of book 1 having been given their final form in the Late Rigvedic period, this book must be included in that period). To begin with, the western academic scholars themselves (see TALAGERI 2008:132-135 for details) have classified the books of the Rigveda into two groups: the family books (2-7) and the non-family books (1, 8-10), and testified, on the basis of their own analyses, that the family books were composed and compiled before the non-family books. Further, they have detached book 5 from the other family books and concluded that it agrees with the non-family books rather than with the other family books. By their analysis, the books of the Rigveda can be classified into three categories: the earlier family books (2-4, 6-7), the later family book (5), and the later non-family books (1, 8-10). This fully agrees with my own classification into Early books (6,3,7), Middle (4,2) and Late books (5,1,8,9,10); except that the Early and Middle books are clubbed together in one category in the western classification, and the internal order within the groups is not analyzed. [In sum, we get four categories: Early family books 6,3,7; Middle family books 4,2; Late family book 5; and Late non-family books 1,8,9,10]"
