Are there easy spells where you dont have to use candles?

To be simple, yes. Pagans can cast spells using nothing but their own energies if that is what must be done. However, the use of stones, herbs, incense, candles, symbols, chants, etc. can allow the spell caster to amplify their powers and concentration on the desired goal(s). I have seen a witch cast powerful magic on the fly with no need for anything other than her own energy. I am not focused enough to do it without any help, but herb bags make for a great alternative to candles. Find the herbs with the properties for the spell you want to cast and collect them all in a bag. Charge them with your energy and then when the time comes for the spell, you call on them along with your own powers to cast.

I was forced to do this many times in college because they didn't allow the burning of anything in the rooms, be it candles or incense.
