The astrological sign known as Cancer the Crab teaches us a spiritual lesson about the benefits of a scavenger. Just like its chemical definition a scavenger is a substance that removes impurities when added to a mixture. Our past activities and experiences leave impurities in our bodies, minds, and spirits. We can use a crab-like impurity removal system to cleanse our feelings of dysfunctional memories that plague our future and limit our successful initiatives. Through quick processing and focusing on our affection for success, we can overcome the painful residues of the past.
