Surya Siddhanta
स्वोच्चापकृष्टा *भगणैः प्राङ्मुखम् यान्ति यद् ग्रहाः। तत् तेषु धनम् इत्य् उक्तम् ऋणम् पश्चान्मुखेषु *च ॥
As many degrees &c., as the planets, being attracted by their apogees, move to the east or the west, so many are called additive or subtractive (to or from their mean places).
english translation
svoccApakRSTA *bhagaNaiH prAGmukham yAnti yad grahAH। tat teSu dhanam ity uktam RNam pazcAnmukheSu *ca ॥
