Meditation on the eight negations 八不. These eight, birth, death, etc., are the 八迷 eight misleading ideas, or 八計 eight wrong calculations. No objection is made to the terms in the apparent, or relative, sense 俗諦, but in the real or absolute sense 眞諦 these eight ideas are incorrect, and the truth lies between them ; in the relative, mortality need not be denied, but in the absolute we cannot speak of mortality or immortality. In regard to the relative view, beings have apparent birth and apparent death from various causes, but are not really born and do not really die, i.e. there is the difference of appearance and reality. In the absolute there is no apparent birth and apparent death. The other three pairs are similarly studied.
