Rahu and Ketu are planets that have no physical body; these are invisible shadow planets. Where the paths of the Sun and the Moon intersect, those two intersecting points are considered Rahu and Ketu, which are mathematical points located on these chakras. The two places where the path of the Moon intersects the path of the Sun, their northern point is called Rahu and the southern point is called Ketu; these are very sensitive and influential points. Despite not having their own existence, they have a very deep impact on human life.
Shadow Planets:
Ketu is a shadow planet, according to Sage Parashar; it has no aspect or ownership of any zodiac sign, but according to many other great astrologers, it has aspects 5, 7, and 9, and Rahu is considered exalted in Gemini and Ketu exalted in Sagittarius; they always move in a retrograde direction.
Origin of Ketu
Let us talk about some Vedic astrological mysteries about the shadow planet Ketu and how Ketu originated. According to the scriptures, when the nectar came out during the churning of the ocean, a war broke out between the gods and demons as to who would get the nectar. Then Vishnu ji came in the form of Mohini and started feeding the nectar to the gods. Then a demon named Rahu sat in the row by deceit, but the Sun and the Moon saw this and told the whole thing to Lord Vishnu. Lord Vishnu ji was feeding the nectar to the gods in the form of Mohini. He came in his form and got angry and separated the demon’s head from the body with his Sudarshan Chakra, but the demon had already drunk the nectar, so he became immortal.
Eclipse (Grahan) by Ketu
The planet Ketu, which got separated from its body due to the Sun and the Moon and remained only in the torso, has the worst effect on the human mind when Ketu is with the Moon. When Ketu is with the moon, the moon is eclipsed; this eclipse dosha eclipses human life.
When Ketu is in conjunction with the moon, the mind remains restless, and there is a habit of always being worried. They are full of useless thoughts and worries; despite having everything, there is overthinking, there is no peace in the mind, and there is a feeling of instability. Such a person can never be satisfied; he feels a heaviness in the chest, and an unknown fear remains. The mind is always restless; there is a habit of doubting and suspecting everything.
This same moon, Ketu, gives very good imagination power but also brings obstacles in achieving good results.
Ketu and Separation/Detachment
People ruled by Ketu feel apathetic and apathetic. Ketu is the factor of beliefs, renunciation, sacrifice, worship, and liberation. In the condition of Ketu, mental state and physical health are affected. The person himself kills his ambitions, due to which he starts inclining towards spirituality, worship, and detachment. Due to its effect, the person becomes unconscious. Ketu detaches from the results of the house in which it is placed. For example, if it is in the fourth house, then it keeps the person away from the happiness of the mother and home. He does not get peace of mind and remains restless. Due to the effect of Ketu, apathy, loneliness, worry, and disappointment are seen in his talks, and he feels restless. This mysterious shadow planet makes the person confused and suspicious.
If someone gets any disease during the period of Ketu, then it is not understood what the disease is, which is not revealed even after getting all the tests done. Due to which man remains in unwanted worries. The native suddenly faces obstacles, the mind remains restless, and he is not able to concentrate on any work or is not able to do it on time; even if he does it, he does it in a hurry. People with Ketu do not trust anyone easily, and it is not easy to understand them. Their character and conduct are not trustworthy because they themselves are delusional and confused. Sometimes they are not able to progress due to their emotionality, blind faith, or dependence on others.
Along with the Rajyog of Ketu, it also gives the result of maraka. If Ketu is with Maraka, it becomes a killer. If it is with Badhakesh, it also gives the result of being an obstacle.
