The Causes of Planetary Strength (Bala)
अथातः सम्प्रवक्ष्यामि ग्रहाणां बलकारणम् । येन विज्ञाय तज्ज्योतिः फलं वक्तुं हि शक्नुयात् ॥
Now I shall explain the causes of planetary strength (bala), by knowing which one becomes able to declare the effects of the luminaries.
Natural Friendships and Enmities of the Planets
सूर्यस्य चन्द्रमा भौमो जीवश्चैव मित्राणि तु । बुधः समः शुक्रार्कौ शत्रू स्यातां न संशयः ॥
For the Sun, the Moon, Mars and Jupiter are friends, Mercury is neutral, while Venus and Saturn are his enemies without doubt.
The Four Grades of Relationship
अतिमित्रं मित्रं समं शत्रुमित्रं शत्रुमित्रकम् । अष्टविधं मैत्रीजालं ग्रहाणां फलसाधनम् ॥
Great friend, friend, neutral, friend-enemy, and enemy-friend — the eightfold net of relationships among planets is the means of determining their results.
