Ketu केतु

The south node — detachment, past-life mastery and moksha.

Ketu, the south lunar node, is the tail of the serpent — the point of detachment and release. It shows what the soul has already mastered in past lives, and therefore now takes for granted, neglects, or seeks to transcend. Wherever Ketu sits, results feel incomplete or are achieved then dismissed; the pull is inward, toward moksha. It can give sudden, uncanny insight and spiritual genius, but also confusion and loss in the worldly affairs of its house. Opposite Rahu always, Ketu is the gate the soul is quietly walking toward.

What Ketu signifies

Ketu is the karaka (natural significator) of detachment, spirituality, moksha, past-life skill, loss, the occult, sudden events, the subtle. In the body it governs acts on the subtle body; linked to undiagnosable ailments and the spine/lower energies. Professionally it favours spiritual work, research, medicine and healing, the occult, mathematics, anything behind-the-scenes.

When Ketu is strong

Intuition, spiritual depth, sudden insight, past-life genius, liberation, healing gifts.

When Ketu is weak or afflicted

Confusion, loss, feeling cut off, accidents, lack of direction, sudden separations.

Dignity — where Ketu is strong and weak

Ketu is exalted in Scorpio / Sagittarius (by tradition) and debilitated in Taurus / Gemini. It rules — (co-rules Scorpio) as its own sign, where it is comfortable and strong. It treats Mars, Venus, Saturn as friends and Sun, Moon as enemies, and is neutral to Jupiter, Mercury. We compute dignity precisely (exalted, moolatrikona, own, friend, neutral, enemy, debilitated) in your live chart using Lahiri sidereal positions.
