SCORPIO (Oct. 23-Nov. 21): Every April, ancient Romans celebrated the festival Robigalia. Among the rites performed were ceremonies to exorcize the god of rust and mildew. Consider reviving that. You benefit from spending a few days waging war against insidious rot. Start by scrubbing away the sludge, scum and gunk from your home, car and work. Make a similar effort on a metaphorical level. Scour muck, glop and grime out of your psyche.
