It is the transit of slow-moving planets that signals a shift in the Karma that is being experienced. Rāhu (Rahu)-Ketu, the shadow planets are specially noteworthy in this regard. They indicate the desires from past lives and in this life which act as Karmic compulsions and are very powerful. Their methods are contrary to the direct motion of the luminaries, Ravi and Chañdra (Chandra)/ the Sun and the Moon, since they are always retrograde.
The chart for the movement of Rāhu in Tulā (Rahu in Tula) and Ketu in Meṣa (Ketu in Mesha) is given below:
Śani and Rāhu (Shani and Rahu) are Vāyu Tattwa Grahas (Vayu Tattwa Grahas) and rule thought. Being airy planets they can fuel debate and this debate can include those relating to sexual acts (Tulā (Tula)/ Libra) and more specifically criminal sexual acts such as rape and unnatural sex. The gangrape which has happened in New Delhi is an instance of this. There will be continued debate and intellectual outpourings on this, but most importantly the masses (Śani/ Shani) and rioters (Rāhu/ Rahu) would remain central to the issue.
