The role of the dasha lord
The dasha lord is the graha ruling the current period. Its role in the reading depends on its sign, its house in the chart, the houses it rules and its dignity.
What it is
In the traditional method, the dasha lord's natal position is read as the core of the period, and its antardasha lord as a refinement. The rule is standard in its outline, though details vary.
How it is worked out or read
The site shows the dasha lord and its years, and leaves the reading of its role to the user and the practitioner.

The lord as a lens
The dasha lord is a lens through which the period is read. Its natal position, its sign, its house and its dignity all shape how the theme of the period is expressed. A dasha lord that is strong and well placed is read as able to carry its theme with ease, while a dasha lord that is weak or in a difficult house is read as needing more effort to express the same theme. The lord is therefore the first thing to examine when a period is described.
The lord's own lordships matter too. A dasha lord that rules a kendra or a trikona brings the themes of those houses into the period, and a reader can see which life areas are emphasised by the lord's lordships. This is one way in which the dasha connects to the rest of the chart.
Mahadasha lord and antardasha lord
Within a period, the mahadasha lord sets the main theme and the antardasha lord colours it. The two lords are read together, and their relation is part of the reading. Friendship, neutrality or enmity between them, as given in the planetary friendship table, is often used to judge whether the combined theme is supported or strained.
A reader who wants to describe a period should therefore name both lords, describe each in its natal position, and then describe the combination, stating clearly that the combination is a traditional judgement rather than a fixed outcome.
Describing the lord carefully
It is easy to make a dasha lord into a single label, such as the planet of wealth or the planet of difficulty. The classical texts give each graha several sides, and the reading depends on context. A careful description names the lord's signs, its houses, its aspects and its lordships, and then indicates which of these are active in the period. This keeps the description tied to the chart rather than to a general label.
Strength, dignity and timing together
A complete reading of a dasha lord brings together its strength, its dignity and the timing of the period. Strength is the general capacity of the planet, judged by its position and aspects. Dignity is its relation to a sign, such as exaltation, own sign or debilitation. Timing is the period itself, which may bring the lord's themes forward at a particular moment in life. The three are read as one picture: a strong and well-dignified lord in its period is read as bringing its themes forcefully, and a weak lord in its period as bringing them with difficulty or in a less direct way.
Because the timing is fixed by the calculation, the reader's task is mainly to describe the strength and dignity honestly and to say how they colour the period. The reading is strongest when it stays close to what the chart actually shows.
