In plain words
It is knowledge that marks happiness out, and happiness is something reached by knowledge — memory itself says, “that happiness was known by me.” On your account, happiness is of the nature of ajñāna, not itself awareness.
Close to the Sanskrit
Because happiness is qualified by knowledge, it is something reached by knowledge; and memory likewise says, “happiness was known by me,” since on your account happiness is not itself knowledge.
