Planetary strength is important for chart prediction. Strong planets will have auspicious effects during their time of influence (Dasas, transits). Weak planets will have inauspicious effects.
Strength of Rasi resp. Bhava lords is another important aspect of the chart. Bhavas will have effects according to their strength and the strength of their lords.
Some sources of strength give hints for special purposes: e.g. Digbala gives informations about directions having positive or negative effects.
The complete Shadbala is the sum of all Balas. Balas are calculated in Rupas or Virupas. One Rupa has 60 Virupas. Most sources of strength have values between 0 Virupas (very weak) and maximum value of 60 Virupas (very strong). Other sources (like Drekkana Bala) have only a maximum value of 30 Virupas.
Parasara gives required values of strength for each planet. Planets meeting these requirements are considered to be strong. These planets will have favourable effects. Planets without strength will prove inauspicious.
