One of the most important factors in the selection of Muhurta is the favourability of the 8th house. This factor, along with the recommendations and general rules of the Vara-Tithi-Nakshatra, was mentioned by the ancient seers.
The 8th house indicates the defect of Muhurta and the negative consequences associated with starting actions during this period. So, any planet located in the 8th house of the beginning of activity will show what unexpected events will accompany the started business. As a rule, a malefic Graha will indicate difficulties and unpleasant events, while benefics can bestow unexpected bonuses and gifts of fate.
