Durga Mantras recited 108 times ( one mala) daily at sunrise can protect against enemies, blockages and even dark energy. The dark energy is generally negative energy and can be even classed as Black Magic depending on how strong it is. For stronger dark energy it is advisable to do 1008 mantras of Durga for 51 days. You can get vibhuti and charge it by reciting 1008 mantras and then use for protection around the house and even on you. Sometimes betel nuts are used to protection by energising through mantras and then putting in temple or carrying on you.
