"O Lord, You first recited the self-manifested, transcendental Vedas. Zīva, the
demigods, and the sages, are not the authors, but are only reciters of the Vedas."
The Vedas do not cease to be a source of genuine knowledge because
sometimes the results promised by it do not occur. This so because the promised
results always occur when the Vedic rituals are performed by properly qualified
persons. When sometimes the promised results do not occur, this means that the
performer of the rituals was not properly qualified. Therefore, because they
contradict the Vedas the saṅkhya- smṛti and yoga-smṛti are not genuine sources of
knowledge.
