Ketu (South node)

Role in the chart

Ketu is the South node, the descending point where the Moon's path crosses the ecliptic. In jyotish it is counted among the nine grahas, and it is always read together with its counterpart, Rahu, the North node. The two move as a pair, six signs apart.

Where Rahu is often described as hunger that reaches outward, Ketu is described as the pull inward. The brief for this graha gives its significations as moksha, detachment, past karma and healing. These four words carry the whole character of the planet. Ketu is not a planet of gain; it is a planet of release. In a chart it shows where the native has already travelled, where effort comes easily because the skill was carried in, and where the ordinary rewards of life tend to feel thin.

Ketu has no own sign in the usual sense; the brief notes that it co-rules Scorpio. It is exalted in Scorpio / Sagittarius and debilitated in Taurus / Gemini. Because the nodes are always opposite each other, these placements tie directly to where Rahu sits in the same chart.

Ketu rules three nakshatras: Ashwini, Magha and Mula. A person born with the Moon in any of these begins life in the Ketu mahadasha. Its weekday is Tuesday.

Strong vs weak placement

Jyotish does not treat the nodes as simply good or bad. A placement is read by sign, house, aspects, and the condition of the planets it joins. What follows is a general description of how the two conditions are usually described, not a judgement about any individual chart.

A well-placed Ketu is often described as giving discernment. The native is not easily pulled by crowd opinion, can let go of what has served its purpose, and may show unusual depth in the field Ketu touches. Because Ketu is linked to past karma, a strong placement is sometimes read as a carried-over competence — something done well without obvious recent training.

A difficult Ketu placement is described in terms of excess rather than lack: over-detachment, a sense of not belonging, difficulty taking ordinary worldly matters seriously, or a tendency to withdraw where engagement is needed. The brief's word healing sits here as well; in many readings Ketu is associated with the quiet, inward work of recovery, though no outcome should be assumed for any person.

Traditional readings differ on how strictly to weigh exaltation and debilitation for the nodes. Some jyotishis give them less force than for the seven grahas; others apply them plainly. Where traditions differ, it is best to say so rather than to pick one.

Effects by house (brief)

House placement is the main way Ketu is located in a chart. A short orientation:

• First house: a detached or self-contained manner; identity built less on outer markers.
• Second house: a complicated relationship with speech, family wealth or stored resources.
• Third house: courage and skill in communication, but uneven interest in routine effort.
• Fourth house: distance from home or a sense of inner rootlessness.
• Fifth house: unusual approaches to learning, children or creative work.
• Sixth house: a strong placement for service, healing work and overcoming obstacles.
• Seventh house: partnership read through detachment; expectations must be examined.
• Eighth house: depth, research, and interest in what lies beneath the surface.
• Ninth house: an unconventional relationship to tradition, teachers and belief.
• Tenth house: career that does not follow the expected line; work done without seeking credit.
• Eleventh house: gains that arrive and are released easily; a small, chosen circle.
• Twelfth house: the classic placement for moksha, retreat and inner practice.

These are orientations only. A full reading requires the whole chart, and a qualified jyotishi should be consulted for any personal question.

Dasha effects

Ketu's period in the Vimshottari system is 7 years within the 120-year cycle. It is among the shorter mahadashas, and in practice it is often described as a period of reorientation rather than accumulation.

Commonly noted themes during a Ketu mahadasha include a turning away from what no longer fits, a period of study or practice, changes in routine, and an interest in matters that are not visible or measurable. Because Ketu is linked to past karma, the dasha is sometimes read as a settling of accounts rather than a fresh beginning.

The antardashas within the mahadasha are read by the planets that rule them, and the whole period is conditioned by Ketu's house, sign and associations in the natal chart. No specific outcome should be promised or feared for any person on the basis of a dasha alone.

Remedies, mantra and gemstone

The traditional beej mantra for Ketu is "Om Sraam Sreem Sraum Sah Ketave Namah", with a customary japa count of 17,000. It is usually taken up with a teacher's guidance and recited with steady regularity rather than in bursts.

The gemstone associated with Ketu is cat's eye (lehsunia). It is traditionally worn only after consulting a jyotishi, since gemstone recommendations depend on the whole chart and are not a general prescription.

Other customary observances include honouring Ganesha, and practices of charity and service. The brief also lists Tuesday as Ketu's weekday, which is when such observances are often kept.

Customs vary by region and family. North and South Indian practice, Smarta and Vaishnava lineages, and amanta and purnimanta calendar conventions all differ in detail, and a family's own tradition is usually the right guide.
