If the 8th House Lord In 1st House then the native does not get material happiness. The native may be a slanderer of God and Brahma. He has wounds or cuts on his body parts. The first house is of self and the eighth house is related to life span, so if the 8th Lord In 1st House, without being related to any malefic or active maraka then the native may have a good life span. If the lord of the eighth house in the first house is related to any malefic or active maraka of the horoscope then it causes a short life.
