Phaladeepika
जीवारशुक्रसौम्यानां दशवसुमप्तेन्द्रियैः क्रमाद्गुणिता । बुधसंख्या शेषाणां राशिगुणाद्ग्रहगुणः पृथक्कार्यः ॥ २६॥
In the case of Jupiter, Mars, Venus and Mercury 10, 8, 7 and 5 are respectively the multipliers while in the case of each of the remaining planets, the multiplier is Mercury's figures, viz, 5. The multiplication by the Graha factors should be effected separately, and should be treated as distinct from the Rasi multiplication.
