5.1 Introduction
There are some special lagnas defined by Parasara. In this book, we will widely use Hora lagna and Ghati lagna and it is time to define them and other special lagnas.
5.2 Bhaava Lagna
Bhaava lagna is at the position of Sun at the time of sunrise. It moves at the rate of one rasi per 2 hours. In the rest of this book, bhava lagna will be denoted by BL.10 If sunrise takes place at 6:00 am and Sun is at 6s 4°47' then, horalagna is at 6s 4°47' at 6:00 am, at 6s 19°47' at 7:00 am, at 7s 4°47' at 8:00 am, 8s 4°47' at 10:00 am and so on. Bhavalagna moves at the rate of 1° per 4 minutes (i.e., 15° per hour).
The following method may be used for computing bhavalagna.
(1) Find the time of sunrise and sun's longitude at sunrise.
(2) Find the difference between the birthtime (or the event time) and the sunrise time
found in (1) above. Convert the difference into minutes. The result is the
advancement of bhavalagna since sunrise, in degrees.
(3) Add Sun's longitude at sunrise (in degrees) to the above number. Expunge
multiples of 360° and reduce the number to the range 0°–360°.
(4) This is the longitude of bhavalagna (BL).
Example 7:
A gentleman was born at 7:23 pm. Sunrise at his birthplace was at 6:37 am on his birthday. At 6:37 am, Sun was at 24°17' in Capricorn. Let us find BL.
(1) 19:23–6:37=12 hr 46 min=12x60 + 46 min = 766 min 10 BL is defined only for the sake of completeness. We will not use it in this book.

(2) Sun's longitude at sunrise is 270°+24°17'=294°17'. Add 766° to it. The result is 1060°17'. Subtracting 360° twice, we get 340°17'. So BL is at 10°17' in Pisces.
5.3 Hora Lagna
Hora lagna is at the position of Sun at the time of sunrise. It moves at the rate of one rasi per hora (hour). In the rest of this book, horalagna will be denoted by HL. If sunrise takes place at 6:00 am and Sun is at 6s 4°47' then, horalagna is at 6s 4°47' at 6:00 am, at 6s 19°47' at 6:30 am, at 7s 4°47' at 7:00 am, 8s 4°47' at 8:00 am and so
on. Horalagna moves at the rate of 1/2° per minute (i.e., 30° per hour).
The following method may be used for computing horalagna.
(1) Find the time of sunrise and sun's longitude at sunrise.
(2) Find the difference between the birthtime (or the event time) and the sunrise time
found in (1) above. Convert the difference into minutes.
(3) Divide the number by 2. The result is the advancement of horalagna since
sunrise, in degrees.
(4) Add Sun's longitude at sunrise (in degrees) to the above number. Expunge
multiples of 360° and reduce the number to the range 0°–360°.
(5) This is the longitude of horalagna (HL).
Example 8:
A gentleman was born at 7:23 pm. Sunrise at his birthplace was at 6:37 am on his birthday. At 6:37 am, Sun was at 24°17' in Capricorn. Let us find HL.
(1) 19:23–6:37=12 hr 46 min=12x60 + 46 min = 766 min
(2) 766/2=383
(3) Sun's longitude at sunrise is 270°+24°17'=294°17'. Add 383° to it. The result is 677°17'. Subtracting 360°, we get 317°17'. So HL is at 17°17' in Aquarius.
5.4 Ghati Lagna
Part 1: Chart Analysis
Ghati lagna is at the position of Sun at the time of sunrise. It moves at the rate of one rasi per ghati (ghati=1/60th of a day, i.e., 24 minutes). In the rest of this book, ghatilagna will be denoted by GL. Ghati lagna is also called “ghatika lagna”. If sunrise takes place at 6:00 am and Sun is at 6s 4°47' then, ghatilagna is at 6s 4°47' at 6:00 am, at 6s 19°47' at 6:12 am, at 7s 4°47' at 6:24 am, 8s 4°47' at 6:48 am and so on. Ghatilagna moves at the rate of 1°15' per minute (i.e., 30° per 24 minutes).
The following method may be used for computing ghatilagna.
(1) Find the time of sunrise and sun's longitude at sunrise.
(2) Find the difference between the birthtime (or the event time) and the sunrise time
found in (1) above. Convert the difference into minutes.
(3) Multiply the number by 5. Divide the result by 4. The result is the advancement
of ghatilagna since sunrise, in degrees.
(4) Add Sun's longitude at sunrise (in degrees) to the above number. Expunge
multiples of 360° and reduce the number to the range 0°–360°.
(5) This is the longitude of ghatilagna (GL).
Example 9:
Let us find GL for the data in Example 8.
(1) 19:23–6:37=12 hr 46 min=766 min
(2) 766x5/4=957.5
(3) Sun's longitude at sunrise is 294°17'. Add 957°30' to it. The result is 1251°47'.
Subtracting 360° three times, we get 171°47'. So GL is at 21°47' in Virgo.
Exercise 8:
A lady was born at 3:11:48 am (hr, min, sec) in the early hours of May 28, 1961. Sun was at 13°1' in Taurus then. Sunrise was at 6:19:18 am on May 27, 1961 at her birthplace. At that time, Sun was at 12°11' in Taurus. Find the longitudes of HL and GL in her chart.
5.5 Comments
(1) If the birthtime changes by one minute, GL will change by 1.25° (i.e., 1°15'). This is quite large and it can cause some error in the position of GL in some divisional charts. So, ghati lagna is more sensitive to birthtime errors than normal lagna. When using GL in divisional charts, we should keep this in mind and try to correct the birthtime based on known events first. Wrong data produces wrong results. Our analysis can only be as good as our data!
(2) Some astrologers don't like dealing with it, but birthtime errors are a fact of life and we have to live with them. If we prefer to choose methods that work in spite of deviation in birthtime by a few minutes, we are ignoring a key fact – there are many people in this world who are born a few minutes apart in nearby places and yet lead significantly different lives. Still some people hide from this fact and stick to methods that give the same results to everyone born in a 15-minute or one-hour or two-hour period, because they don't have to deal with the complicated issue of birthtime errors then! But that's not the right approach – we should give importance to finer techniques. After all, Sage Parasara must have written about all these fine techniques only because he thought they were useful.
(3) Some people define sunrise as the time when the center of the visual disk representing Sun rises on the eastern horizon, i.e., the time when lagna and Sun are exactly at the same longitude. Some other people consider sunrise as the time when the upper tip of the visual disk representing Sun appears to be rising on the eastern horizon, i.e., the time when the first ray of Sun is seen. The latter
approach is recommended.
Exercise 9:
Suppose (just suppose) that a key event from the known past of the lady of Exercise 8 makes us think that her GL has to be between 16°15' and 17°30' in Virgo. Correct
the given birthtime accordingly.
5.6 Use of Special Lagnas
Use of special lagnas will become clearer in future chapters. For now, it will suffice to say that hora lagna shows money and ghati lagna shows power. In any chart, normal lagna shows self. Hora lagna shows self, from the point of view of money, wealth and prosperity. Ghati lagna shows self, from the point of view of fame, power and authority. For example, when we time good and bad periods for a
businessman, hora lagna may be very important. When we time good and bad periods for a politician, ghati lagna may be very important.
5.7 Sree Lagna
In Sanskrit, the word “Sree” means wealth. It also means Lakshmi, wife of Lord Narayana and goddess of wealth. Sree Lagna will be denoted by SL in the rest of this book. Sree Lagna is important for prosperity. Its use will be shown in the chapter on
Sudasa. Computation of Sree Lagna will be explained for now.
(1) Find the constellation occupied by Moon.
(2) Find the fraction of the constellation traversed by Moon.
(3) Find the same fraction of the zodiac (360°).
(4) Add this amount to the longitude of lagna. Subtract multiples of 360° if
necessary. The resulting amount is the longitude of Sree Lagna (SL).
Example 10:
Let us take a native with Moon at 13 Li 06 and lagna at 25 Vi 05. Moon’s longitude is 180° + 13°6' = 193°6'. Lagna’s longitude 150°+25°5' is 175°5'.
(1) Moon is in Swathi constellation, which runs from 6°40' to 20°0' in Libra.
(2) Moon’s advancement in his constellation is 13°6' – 6°40' = 6°26'. As fraction of
the whole constellation, this is (6°26')/(13°20') = 386'/800' = 0.4825.
(3) The same fraction of the zodiac is 0.4825 x 360° = 173.7° = 173°42'.
(4) Adding this amount to the longitude of lagna, we get 175°5' + 173°42' = 348°47.
This is the longitude of SL. So SL is in Pisces at 18°47'.
Exercise 10:
Suppose someone has Moon at 15 Le 29 and lagna at 14 Sc 19. Find the longitude of SL (Sree Lagna). Warning: There are some more special lagnas defined by Parasara, but they are
beyond the scope of this book. We will restrict ourselves to the ones defined in this book.
