Directional strength is the strength that a planet attains due to its unique positioning in a birth chart. Directional strength is most popularly called as “Dishabala” in Vedic astrology. Because of this strength a planet’s ability to effect positively or negatively is enhanced drastically. What it means is that if a planet is a “Karaka Graha” in a birth chart and if it becomes Dishabali or gets directional strength its Karakatwa or ability to do good is enhanced significantly. Similarly a “Maraka Graha’s ” ability to do bad is also increased if it becomes Dishabali. Below is the image which shows different places in a birth chart where a planet becomes Dishabali. 

Jupiter and Mercury
These two planets become Dishabali or get the directional strength in the 1st house or the ‘Pratham Bhava’ no matter what rashi is in the 1st house. This is regarded as the East of a zodiac or birth chart.
Jupiter represents knowledge where as Mercury represents ‘Buddhi’ or intellect. So if either of the planets are in the 1st house on a birth chart and if they are “Karaka Grahas” in that kundali then the person will be wise and knowledgeable. But if they are Marakas in a kundali then the reverse will be true. The person might be idiotic and dumb.

Sun and Mars 
These 2 become Dishabali in the 10th house of a birth chart which is regarded as the South of a zodiac or Bhachakra. If Sun is a ‘Karaka’ he will give positive results regarding government and administrative work,the person will have a powerful personality and become successful in his/her profession. Maraka Sun will give the opposite results here. Similarly Mars is also Dishabali in this house who will give positive or negative results according to his ‘Karakatwa or Marakatwa’.

Saturn
Saturn becomes dishabali in the 7th house. His directional strength comes from the West side of the Zodiac or Kundali. A karaka Saturn in this house will solidify partnerships and will give a stable relationship with the spouse. Saturn will also effect greatly on one’s own personality and make him stable. The reverse is also true if the Saturn is a Maraka in this chart. He will disrupt marriage and partnerships. Will cause difficulties in daily wages.

Moon and Venus  
These 2 planets become ‘Dishabali’ in the North direction or the 4th house in a birth chart. Moon represents mind and mother while Venus represents all the luxuries and worldly pleasures. So ‘Karakatwa” will cause positive results in these regards. If Moon is a Maraka and is placed in the 4th house in a Kundali he may affect the relationship with the mother and cause mental tensions. A ‘Maraka’ Venus will cause difficulties in gaining all the luxuries and other materialistic pleasures. He might also affect sexual health adversely.
