Rahu is the ascending lunar node and Ketu the descending lunar node, the two opposite points where the Moon’s orbital path crosses the ecliptic. Jyotisha treats them as grahas within interpretation and timing even though they are not physical planets.

Start with the calculated eclipse axis
The two nodes are always opposite by definition. Software may offer mean or true nodes, so record that choice together with zodiac and ayanamsha before comparing degrees or signs across charts.
Astronomical calculation identifies the crossing points; it does not prove symbolic effects. Keep the reproducible coordinate separate from traditional language about appetite, disruption, detachment, ancestry, or liberation.
Rahu and Ketu describe contrasting functions on one line
Rahu is often associated with amplification, pursuit, unfamiliar territory, visibility, and boundary crossing. Ketu is often associated with cutting, release, concentration, discontinuity, and what feels already known or difficult to sustain.
These are interpretive starting verbs, not moral labels. Rahu is not automatic worldly success and Ketu is not automatic spirituality; either can coincide with skill, confusion, attention, or avoidance depending on chart context.
Reading rule
Keep calculated values, lineage rules, and context-dependent interpretation in separate layers.
Read house, sign lord, conjunctions, and aspects
Locate both houses from Lagna, then inspect the lords of their signs, any close conjunctions, and aspects accepted by the lineage. Nodes are commonly said to borrow or transmit qualities from their dispositors and associated grahas.
An isolated sign description omits the axis: emphasis in one house necessarily places the other node opposite. Ask how the two life domains compete, alternate, or require integration rather than interpreting each node as a separate personality.
Separate natal placement from dasha and transit activation
A natal node axis belongs to the base chart. Rahu or Ketu Mahadasha, Antardasha, or a transit over a sensitive point is a timing layer and should be labeled rather than turned into a permanent trait.
Inspect the active lords, natal condition, relevant houses, and corroborating transits before describing themes. A node period cannot name a guaranteed marriage, migration, illness, career leap, or spiritual event.
Eclipse mythology does not justify fear-first advice
Mythic stories and ritual traditions are part of the cultural history of Rahu and Ketu, but a consultation should not convert them into proof of curses, possession, or inevitable loss. Cultural practice can be discussed without coercion.
Avoid urgent gemstones, rituals, donations, or purchases presented as the only way to prevent harm. Present-tense safety, medical, legal, and financial problems require relevant evidence and qualified support.
Worked example: Rahu in the tenth and Ketu in the fourth
Assume a verified chart places Rahu in the tenth house and Ketu in the fourth. Record both sign lords, conjunctions, aspects, Moon and Lagna condition, and whether a node period is active before proposing a public-versus-private axis.
The useful question may concern how visibility and work demands interact with rest and home continuity. It is not proof of fame, exile, family rupture, or a specific career; lived circumstances can support or contradict the hypothesis.
The nodes are traditional symbols, not causes of events
Rahu and Ketu are mathematically defined lunar nodes, while their personality and fate meanings belong to astrology. Correct node calculation does not validate a prediction.
Do not use node labels to diagnose mental health, stigmatize a person, or direct consequential decisions. State settings, uncertainty, lineage rules, and real-world evidence.
