In plain words
Just as a lamp does not need another lamp to reveal it, consciousness requires no outside light. Because awareness is the very nature of the Self, no second awareness is ever needed.
Close to the Sanskrit
For there is no need of another lamp, just as in the illumination by a lamp; [and] because awareness is of the nature of the Self, another awareness is not thus accepted.
