How long is Rahu mahadasha?

Eighteen years — the second longest after Shani's nineteen.

Is Rahu mahadasha always difficult?

No. Rahu amplifies what it touches. In a chart where it sits in a strong house with a well-placed dispositor, these are often the years of the biggest external gains. The difficulty attributed to Rahu comes from its restlessness, not from a fixed malefic verdict.

Why does Rahu have no sign of its own?

Because it is a shadow point rather than a physical body — the north node of the Moon's orbit. Classical practice therefore reads it through the lord of the sign it occupies, called its dispositor.

What are the remedies for Rahu mahadasha?

Tradition suggests the Rahu mantra, donating sesame or a blanket, serving those who are marginalised, and — the practical half — resisting shortcuts. Rahu's classical difficulty is with means, not with ends.

What happens during Rahu mahadasha?

Rahu mahadasha runs for 18 years — long enough to reshape a life. Rahu is a shadow point rather than a body, associated with ambition, foreign things, sudden rise and the appetite for what one does not yet have. It has no sign of its own, so it acts largely through the sign and house it occupies and the planet that rules them.

Why Rahu is read through another planet

Rahu is not a planet but the north lunar node — a calculated point where the Moon's path crosses the ecliptic. Because it owns no sign, classical practice reads it largely through its dispositor: the lord of the sign it occupies. Rahu in Mesha is read through Mars, Rahu in Karka through the Moon. This is the single most useful key to an eighteen-year Rahu period — the question is not only where Rahu sits, but what condition its dispositor is in.

Eighteen years is long enough to change the terrain

Rahu's is the second-longest mahadasha after Shani's nineteen. Because it usually spans a whole phase of adult life, it is often the period in which someone's circumstances change out of recognition — a move abroad, a new field, an unfamiliar social world. Classical texts associate Rahu with amplification and with things obtained unconventionally. The unglamorous reading is that Rahu enlarges whatever it touches, which is favourable when it touches a strong house and difficult when it does not.

Rahu's antardashas and the Kaal Sarp question

The eighteen years contain nine antardashas, and Rahu-Guru, Rahu-Shani and Rahu-Shukra are among the longest sub-periods anyone runs. Readers whose charts also carry Kaal Sarp yoga often ask whether a Rahu mahadasha makes it worse. The honest answer is that the two are independent — Kaal Sarp is a whole-chart arrangement, the mahadasha is a timeline — but a chart carrying both is a reasonable case for a full reading rather than a rule of thumb.
