Jyotisha commonly works with nine grahas: the Sun, Moon, five visible planets, and the two lunar nodes. Rahu and Ketu are mathematical points rather than physical planets, yet they function as grahas within the interpretive system.

Start with function, not good-versus-bad labels
Surya is associated with visibility and authority; Chandra with mind, responsiveness, and care; Mangala with force and action; Budha with discrimination and exchange; Guru with counsel and expansion; Shukra with attraction and value; and Shani with limits, labor, and time.
These are starting verbs, not verdicts. A so-called natural benefic can overextend or attach, while a natural malefic can supply endurance, boundaries, or decisive effort. Functional results also depend on the ascendant and the houses a graha rules.
Rahu and Ketu are nodes with a special chart role
Rahu and Ketu mark the intersections of the lunar and solar paths used to describe eclipses. They do not own physical bodies like Mars or Jupiter, but many Jyotisha traditions assign them strong symbolic and timing roles.
Interpretations vary by lineage. A careful reading states how the nodes borrow from their sign lord, dispositor, conjunctions, aspects, and house rather than treating Rahu as automatic success or Ketu as automatic spirituality.
Reading rule
Keep calculated values, lineage rules, and context-dependent interpretation in separate layers.
Judge a graha through several layers of condition
Record sign, house, sign lord, house ownership, dignity, combustion or retrogradation rules used, aspects, conjunctions, and divisional-chart support. Not every school weights these layers in the same order, so method names matter.
The Moon also anchors nakshatra-based timing in common Vimshottari practice, while the ascendant sets the house framework. This is why a list of generic planet meanings cannot substitute for a calculated chart.
Natural and chart-specific relationships are different
Texts and teaching lineages describe natural friendships and enmities among grahas, while temporary relationships arise from chart position. House rulership can make the same graha function differently for different ascendants.
Instead of saying “Saturn is bad,” ask what Saturn owns, where it is placed, what it contacts, and whether its period is active. That sequence turns an inherited label into an auditable chart statement.
Use a repeatable reading order
Confirm birth data, zodiac, ayanamsha, and house framework. Identify the ascendant and Moon, then describe each graha’s basic function, ownership, sign and house condition, relationships, and timing activation.
Only after those steps should you synthesize recurring themes. Give more weight to patterns repeated across several independent indicators than to one dramatic placement.
Worked example: describing Mars without diagnosing a person
Imagine a hypothetical chart with Mars in the tenth house. This is not a real-person reading. Begin with action and contest in the field of public work, then check the sign, house lordship, dispositor, aspects, and whether a Mars period is active.
Possible expressions might include decisive leadership, technical effort, conflict with authority, or work that rewards speed. The chart does not choose one on placement alone; lived context and the rest of the chart narrow the hypothesis.
Grahas are a traditional symbolic framework, not measured causes
Astrological symbolism is not a scientifically validated diagnosis or event forecast. Keep calculation facts separate from interpretive claims, and do not infer health, character, or danger from a single graha.
Use the framework for study and reflection. Medical, legal, financial, and safety decisions require relevant evidence and qualified professional advice.
