Empowering the 12th House [astrology]?

[Light Yagami]

Hey.
In JoS Astrology, it says that the 12th House, along with its positive aspects [spirituality] has many negative aspects... So, what if one has a planet in that House, but they want to empower that planet [for spiritual purposes]? Will the negative aspects [along with the positive aspects] of the 12th House be empowered as well? :/
