Challenge: The persistent presence of evil spirits can cause ongoing distress and disruption. Counter with reinforcement rituals like purification ceremonies, prayer, and spiritual cleansing to maintain a protective barrier and prevent re-entry.

Effective Countermeasures: Implement protective measures like amulets, talismans, or sacred objects to create an unwelcoming environment for evil spirits. Strengthen inner defenses through meditation, mindfulness, and positive affirmations to cultivate an impenetrable spiritual core.
