Drekkana

However, Rudra states that some interpret the said Parasari rule as lords of the 5th and the 9th navamsas whereas the Kalpa Latha of Somanatha states that the twelve drekkanas from Mesha ('Aries') to Karaka ('Cancer') will have for their lords, the rulers of the twelve signs, in clock-wise symmetrical order from Mesha and similarly for the rest i.e. from Simha ('Leo') and from Dhaunus ('Sagittarius').

And, there is also the Parivritti Thrayapaksha method recommended in the Vriddha Karikas of Jaimini which suggests the lordship as per the scheme followed while erecting the Navamsa Chart.

A planet occupying its own drekkana confers virtues; the Moon similarly situated endows one with best of qualities of body and mind, and the lord of the lagna occupying the first, second or the third drekkana makes one a judge, a ruler of a mandal or head of a village i.e. attain high position respectively.

[5] B V Raman in his book, “How to Judge a Horoscope (Vol.1)” has explained the impact of planets in various drekkanas and their lords on the financial position of individuals.

c) If Venus or the Moon is in debilitation sign in the 4th house and the lord of the 7th occupies a Pasa or Sarpa drekkana, wife will die by hanging.

Venus situated in a cruel drekkana gives fear from enemies, imprisonment and great misery, chains and troubles from robbers.
