Ketu is the South Node of the Moon. Like Rahu, it’s not a physical planet. It is a point in space where the Moon”s orbit crosses the ecliptic. In Vedic astrology, Ketu represents your past life experiences. It shows what you bring into this life as natural talent. It also shows where you need to let go. Ketu energy is spiritual, detached, and sometimes confusing.

Your Ketu placement reveals what you mastered in previous lifetimes. You don’t need to work on Ketu areas because you already did the work. The problem is that Ketu energy feels so natural that you overuse it. You fall back on your Ketu strengths instead of developing your Rahu strengths. A person with Ketu in Aries is naturally independent and courageous. They need to learn cooperation and compromise through Rahu in Libra.

Ketu rules spirituality and detachment. When Ketu activates a part of your chart, you lose interest in material things. You might give away possessions, end relationships, or withdraw from society. Ketu asks you to release what no longer serves you. It strips away attachments until only the key remains. That process feels painful but it clears space for growth.

In Vedic mythology, Ketu is the body of the demon Rahu. After Rahu”s head was cut off, the body became Ketu. It floats through the cosmos without a head. That image captures Ketu energy perfectly, ketu is the body without the mind. It acts without thinking. It knows without learning. Ketu is intuitive rather than intellectual, you can’t explain Ketu wisdom. You can only feel it.

Ketu takes about eighteen months to move through each sign. It moves backward through the zodiac just like Rahu. Ketu always sits exactly opposite Rahu in your chart. The Rahu-Ketu axis is the most important karmic line in your birth chart. It shows the balance between past life skills and future life goals. Your growth happens when you move from Ketu toward Rahu.

Ketu doesn’t rule any signs but is exalted in Sagittarius and debilitated in Gemini. In Sagittarius, Ketu expresses spiritual wisdom naturally. Wisdom flows without effort. In Gemini, Ketu struggles because Gemini wants variety and connection while Ketu wants solitude and focus. The sign placement of Ketu colors how your detachment shows up.

The house placement of Ketu shows where you detach. Ketu in the 1st house makes you spiritually oriented from a young age. You don’t care about appearances or social status. Ketu in the 4th house means detachment from family and home. You might move far away or choose an unconventional living situation. Ketu in the 7th house brings detachment in relationships. You feel complete without a partner, ketu in the 10th house means detachment from career. You do not care about fame or recognition.

Ketu rules enlightenment and liberation. In Vedic philosophy, the goal of life is moksha, or liberation from the cycle of birth and death. Ketu energy moves you toward that goal, it reduces your attachment to the material world. That is why Ketu periods often feel lonely. You lose interest in things that used to matter. But that loneliness is really freedom in disguise.

Ketu also rules healing and psychic ability. People with strong Ketu placements often have natural healing gifts. They sense energy, they know things without being told. They dream prophetically. These abilities come from past life training. If Ketu is active in your chart, trust your intuition. It knows more than your logical mind does.

The shadow side of Ketu is confusion and lack of direction. Ketu energy feels foggy. You don’t know what you want, you feel disconnected from your own desires. That is normal for Ketu. The planet does not want anything in the material world. Its desires are spiritual. When Ketu confuses you, the answer isn’t to push harder. The answer is to let go and trust the process.

Ketu periods in Vedic astrology last seven years. During Ketu mahadasha, you feel pulled toward spirituality. You might lose interest in career, relationships, or material success. Ketu periods are excellent for meditation, healing work, and spiritual study. They’re not good for starting new businesses or pursuing ambitious goals. Ride the Ketu wave instead of fighting it.

Ketu rules the lower body, particularly the legs and feet. In medical astrology, Ketu is associated with circulation issues and problems with the lower extremities. Ketu natives might experience cold feet, varicose veins, or restless legs. Movement helps Ketu energy flow. Walking, dancing, and yoga all support Ketu health by grounding scattered spiritual energy.

The planet also rules your relationship with endings. Ketu governs the natural conclusion of cycles. When something ends, Ketu is involved. Ketu natives experience many endings in their lives. Relationships, jobs, and homes come and go. Each ending feels like a small death. But each ending also clears space for something new. Ketu teaches you to let go gracefully.

Ketu rules solitude and isolation, people with strong Ketu placements need alone time. They recharge in silence, they can’t be around people all the time. That need for solitude isn’t antisocial. It is spiritual. Ketu natives process energy differently. They absorb the emotions of others and need time to release that energy. Creating space for solitude is key for Ketu health.

The planet also rules your relationship with your body. Ketu natives often have a complicated relationship with their physical form. They might forget to eat, they might neglect their appearance. They might feel like their body is a cage for their spirit. Ketu teaches you to honor your body as a temple even when you feel disconnected from it. Your body is the vehicle for your spiritual journey.

Ketu transits bring major spiritual shifts. When Ketu transits a sensitive point in your chart, you might feel called to simplify your life. You might get rid of possessions, end relationships, or change your career. These transits feel disruptive but they clear space for your soul growth. Ketu transits aren’t the time to start new things. They’re the time to release what you no longer need.

Ketu also rules your sense of direction in life. People with strong Ketu placements often feel directionless in a traditional sense. They don’t have a five-year plan. Mereka live moment to moment. That lack of planning can create instability but it also creates freedom. Ketu teaches you to trust the journey without needing to control every outcome. You’re exactly where you need to be.
