Resins can be very purifying, uplifting, and beneficial. Many resins carry the essence of beautiful scents that have the ability to redirect, clear, or bring sacredness to a space. When burning naturally derived resins, as the smoke emits it's aroma the space can become uplifted. Using resins as a means of clearing is a great way to remove stagnancy from a space. Naturally occurring resins can be found in trees. Resins such as dragons blood, amber and pine are popular examples tree resins (many times these resins are formed in the bark of trees). Frankincense is one of the most precious resins used; it is harvested from the Boswellia tree. It doesn't take much of a resin to bring its sacredness to a space. A small amount will usually do just fine.
