I found this on the Aish website:
The accurate meaning of “Torah” is twofold. Firstly it comes from the word “הוֹרָה,” which means teaching. More precisely it means “teaching with direction,” i.e. the type of teaching which enables and empowers one with a direction to proceed. The same word could be used in Hebrew with such teachings both in spiritual and secular realms.
The second meaning is from the word “אורה,” which means light. One example of this reflected in the verse which states, “A mitzvah is a candle, and Torah is the light” (Proverbs 6:23).
Would someone please help me out to see the connection? Both hebrew words hora'ah and orah come from different roots, that's why I don't understand the connection being made.
