Brihat Parashara Hora Shastra
तदा स्वमात्रशेषः स्यादन्ये नश्यन्ति सोदराः । तृतीये लाभगे केतौ बहुलं भगिनीसुखम् ॥ ३६॥
If Śani is alone in one of the said Bhavas, the native will be spared, while the co-born will die. Ketu in the 3rd, or the 11th will give abundant happiness from one‟s sisters.
english translation
