Brihat Parashara Hora Shastra
पिण्डायुरिव तत्रापि हानिं कुर्याद् विचक्षणः । अत्राऽपरो विशेषोऽपि कैञ्चिद् विज्ञैरुदाहृतः ॥ २०॥
The same reductions, as per Pindayu, apply to Ańśayu as well; i.e. half for a combust Grah, one third for inimical placement and the ones, due for placements in the half of the zodiac, counted from the 12th backwards.
english translation
