Purple candles are great for setting sacred space in psychic phenomena. Best practice is to set the intention that you are creating for four corners of sacred space and within that container all is well. The connection is to the Divine only and in unconditional love. Setting intentions, spell work, and psychic protection, sacred space. They're great for use on altars, in rituals and ceremonies, and breaking spells. You can oil the candle with an aromatic oil, then speak your intention directly into it and light the candle. Let it burn all the way through, do not leave unattended.
