Generally, all planets move from one Rasi to the other in clock-wise direction.
Rahu and Ketu move in anti clock-wise direction. Sometimes, we see that a planet,
instead of moving in clock-wise direction in the Zodiac seems to be moving in anti clockwise
direction. Whenever a planet is moving in anti clock-wise direction in the Zodiac, it
is said to be in Retrogression. Sun and Moon will never retrograde. Rahu and Ketu are
always in retrogression.
A retrograding planet will always aspect the rear sign with half aspect. A
retrograding planet will give beneficial results, if a friendly planet is placed in the 12th Sign
from retro planet. It will give bad results if an enemy planet is placed in the 12th Sign from
retro planet. So, let us analyze few example charts.
Example 1:
In the above chart, Guru is in retrogression in Kataka Rasi. Ketu is located in the
9th Sign (Same Direction) from Guru. Ketu is Mokshakaraka and he is aspecting Guru.
Therefore, the native will be a sanyasi. Sukra is located in the 12th Sign from the Guru,
and Sukra is aspected by Chandra (Chandra is in 9th Sign from Sukra). Sukra and
Chandra, both are beautiful ladies. Guru is running towards Sukra in retrogression.
Therefore, the native, a sanyasi is running after beautiful ladies.
Ex 2:
In the above chart, Guru is in retrogression in Kataka Rasi along with Chandra
and Sukra. Ketu is located in the 12th Sign from Guru. The planets Chandra and Sukra
both are females, Ketu is Mokshakaraka. Here, in the beginning the native will come
across many beautiful ladies. He will be troubled by these ladies. Finally, he will run
away from these ladies and takes Sanyasa, because Guru is running towards Ketu in
retrogression.
Ex 3:
In the above chart, Sani is in retrogression in Tula Rasi. In the 2nd sign from
Sani, Kuja is located. In the 12th Sign, Guru is located. Kuja is dead enemy of Sani. Guru
is a friendly planet for Sani. Sani is a Karma-karaka, the significator of profession. Here,
the native suffers from enemy harassment in professional career (Kuja is a karaka for
enemies). Sani in retrogression approaches Guru for help, therefore the native
overcomes the difficulties with the help of a friend.
Ex 4
In the above chart, Guru is in retrogression in Tula Rasi. In the 2nd Sign from Guru, Rahu
is located in Vrischika. In the 12th Sign from Guru, Surya is located in Kanya. Rahu is
the mouth of Kala purusha is trying to swallow the Jeeva karaka, Guru. Guru is afraid of
Rahu. Therefore, Guru is running towards Surya for his help. Surya is paramatma.
