The 8th house - the house of other people's resources (energy, money). The house of death and conception (as a gateway to another world). The house of crises. And here Mars is strong. Symbolically, this is his house, this is the house of crises. Such a person is activated in critical situations and can resolve this situation.
How exactly the person acts in this crisis will be shown by the sign in which Mars is located. We understand that if Mars is strong in sign, then the person is brave and decisive in both ordinary situations and crises, as this is inherent in him essentially. Such a person is really not afraid to take risks. Well, and if Mars is in a weak sign for itself, let's say, in Cancer or in Pisces, then what? Crises do not happen every day in life, and in ordinary life the person can behave characteristically of his sign, somewhere he will be lazy, somewhere not straining, somewhere working, somewhere being active to some extent. But as soon as a situation occurs that touches, seriously hooks him, his loved ones, his family, he is activated. Ready to turn the world upside down, but to do the impossible, he turns on some hidden forces. Or, when faced with such conditions, he begins to show physical superhuman efforts.
With this position, there may be health problems that lead to operations. May indicate accidents, serious injuries that require quick intervention.
Professionally, this energy can be realized through critical professions - surgeons, police, emergency services, firefighters, tax inspectors.
