Two traditions, two names and two different counting rules share this division, and most confusion about it comes from nobody saying which one is on screen. Here is the one used on this site, and why it matters.

The chart every career reading leans on is worth half a point out of twenty in the classical strength table. That gap between formal weight and practical use is worth understanding before you read it.

The Navamsa is the only varga whose divisions line up perfectly with the nakshatra padas, and the only one classical writers allow to overrule the birth chart on a question of strength.

Eight parts of three degrees forty five minutes, counted the way the Navamsa counts. It is the chart people reach for when they want to know about death, which is the worst possible reason to open it.

Seven does not divide thirty degrees into anything tidy, which is part of what makes this chart distinctive. It is also the single varga whose addition turns the six-chart strength scheme into the seven-chart one.

Six parts of five degrees, and for fixed signs the count begins from the eighth. Whether or not that was designed, it puts the chart of illness on the house the tradition gives to what does not resolve.

Six signs out of twelve, and no rule in Parashara to appeal to. This is one of four vargas the classical text never defines, which changes how much weight it can carry.

Four quarters of seven and a half degrees, counted to the first, fourth, seventh and tenth sign. Those are the four angles, so the chart of what you own is built out of nothing but kendras.

Ten degrees each, counted to the first, fifth and ninth sign. Those are the trines, so a planet's third can shift its sign but never its element, and the chart of courage is locked to the element you were born with.

Every planet in this chart lands in one of two signs. That is not a limitation of the method, it is the method, and it turns the D2 into a sorting question rather than a chart reading.

Its divisor is one, so nothing is divided and no planet moves. That sounds like a technicality until you notice it is the reason every other chart is subordinate to this one.

Dhana Bhava governs speech and accumulated wealth in the same breath, which is an odd pairing until Budha lands there and joins them. Then the voice stops being a manner and becomes an instrument that money arrives through.
