The uniqueness of this book is to treat the Buddha’s notion of rebirth not as a spiritual phenomenon, but literally as the repeat or purity of birth in the same line that is motivated by prejudice.
The eighty-five lessons address the pain that this compelled lineage descent brings. They address the Buddha’s practice of nonidentity or anatta that allows one to escape rebirth, and the joy of nirvana that this brings.
Thus the notion of rebirth is preserved in a rational way—in the desire that exists in all societies to perpetuate lineage. Likewise, the notion of anatta or nonidentity is preserved in the need to refute the stigma and stereotype that is directed at lineage.
