Chakra Candles

Some admin and tidying at home this morning. My daughter called to drop off two Christmas presents that were left with her after I left at Christmas because they were heavy on top of my case and other gifts.
The picture is one of them and they all smell lovely. They are chakra candles. A colour and scent for each one. I am not sure what they are meant to achieve but they are lovely scented candles.
The picture is not great but was the best I could manage.
The scents are :-
Rose, ylang ylang, lemon, jasmine, eucalyptus, lavender and lotus.
