It is said in the shulchan Aruch that one should buy Shabbat Candles instead of Wine if one didn't have enough money for both of them. However, When we see into the talmud it says in Shabbat 23b that a person must choose Candles because there cannot be shalom without light. But then again, we have electric lights nowadays which can also replace candles in times of need. And if someone was to talk about the spiritual lights from the candle as the Zohar talks about them, i have read that Rabbi Ovadia Yosef says that someone should not posek with regards to Kabbalistic concepts. So then, Should one theoretically choose wine or candles?
