Can I light candles without having pictures or personal items of my target ?

I don't use anything with Da other than my chants.

Some of the candles use chants, some use a petition. Using a petition on the wrong one could result in you sending the desired result to them, not yourself. I.e., deadly attraction could make them irresistible to everyone else instead of making you irresistible to them.

Which candles specifically?

Yes you can just include they name And birthdate if you know it
