If you have looked at a computer-made horoscope, you have probably seen two charts that look almost the same: the rasi chart and the Bhava Chalit chart. In the second one a planet or two may sit in a different house. Which chart is right, and why are there two?
The short answer is that they answer different questions. The rasi chart shows which sign each planet is in. The Bhava Chalit chart shows which house each planet falls in when the houses are measured from the exact degree of the Lagna.
A sign (rasi) is a fixed 30° slice of the zodiac. A house (bhava) is an area of life measured from the point that was rising at birth.
The simplest way to match them is to say: whatever sign the Lagna is in becomes the whole first house, the next sign the whole second house, and so on. This is the whole sign method, and it is what the ordinary rasi chart shows.
But the Lagna is not a whole sign. It is one exact degree. Suppose the Lagna is at 25° Aries. Only the last 5° of Aries rise after that point; most of Aries had already risen before birth. The whole sign method still treats all of Aries as the first house. The Bhava Chalit chart asks a sharper question: measured from that exact rising degree, where do the houses really begin and end?
Chalit means "moved". It is the chart in which planets have moved to their true houses.
Each house has a middle point (bhava madhya), where its effect is strongest, and a junction (bhava sandhi) with the next house, where it is weakest.
The easiest version is this:
A more traditional version, named after the astronomer Sripati, uses two measured points: the Lagna degree and the degree of the 10th house (the point highest in the sky, the midheaven). The 7th and the 4th are opposite to these. The arc between each pair of angles is divided into three equal parts to give the middles of the houses in between. Because the distance from the Lagna to the midheaven is seldom exactly 90°, the houses come out unequal: some wider than 30° and some narrower.
The Krishnamurti system uses the Placidus houses of Western astronomy and treats each cusp as the start of a house, not its middle. A KP chart can therefore place planets differently from a traditional Bhava Chalit chart.
When you compare charts from two programs and a planet is in different houses, check which method each one uses. That is nearly always the reason.
Take a chart with the Lagna at 25° Aries and use the equal house method.
Now place three planets:
| Planet | Position | House in rasi chart | House in Chalit chart |
|---|---|---|---|
| Mars | 5° Aries | 1st | 12th |
| Venus | 8° Taurus | 2nd | 1st |
| Jupiter | 12° Taurus | 2nd | 2nd |
Mars is in the sign Aries, the sign of the Lagna, so the rasi chart puts him in the first house. But he is 20° behind the rising degree, on the other side of the house boundary at 10° Aries. In the Chalit chart he is in the 12th house.
Venus is in Taurus, the second sign, but only 13° ahead of the rising degree. She is still within the first house.
Jupiter stays in the second house in both charts.
Notice what has not changed: Mars is still in Aries, his own sign. Venus is still in Taurus, her own sign. Only the house has shifted.
A planet changes house only when it is on the far side of a house boundary from the Lagna degree. As a rough guide for the equal house method:
A planet never moves more than one house in the equal method.
This is the working rule most traditional astrologers follow.
From the rasi chart, read:
From the Bhava Chalit chart, read:
In the example above, Mars rules the Lagna and sits in his own sign, so he is strong and gives the confidence of a good Lagna lord. But his results as an occupant lean toward 12th house matters such as travel, expenses and work in distant places. Both statements are true together.
A simple way to hold it: the rasi chart shows the quality of a planet; the Chalit chart shows the place where it delivers.
A planet within a degree or two of a house junction is said to be in bhava sandhi. Tradition treats it as weak for house results, because it does not belong clearly to either house. It may give a little of both. This is not a serious flaw; it only means you should not build a firm prediction on that planet's house position.
The rasi chart treats each sign as one house. The Bhava Chalit chart measures the houses from the exact Lagna degree, so a planet near the edge of its sign may fall in the previous or the next house. Use the rasi chart for signs, dignity, lordship, aspects and yogas, and the Chalit chart to refine where and how strongly a planet gives its house results. They are two views of the same sky and are meant to be read together.
It is a chart that places each planet in a house according to the exact degree of the Lagna, with the Lagna degree at the middle of the first house, in place of treating each whole sign as one house.
Because the houses of the Chalit chart do not start where the signs start. A planet near the beginning or end of a sign can fall on the other side of a house boundary and so belong to the previous or the next house.
Both are used. The rasi chart is the basis for signs, dignity, aspects, yogas and house lordship. The Chalit chart refines which house a planet gives its results in.
Bhava sandhi is the junction between two houses. A planet very close to that boundary is considered weak in giving the results of either house.
