We are starting a series on mathematical aspect of astrology and today's post is about calculating the duration of signs at any place. In this post we are going to study the meaning of Rasinamas, Charakhandas, calculation of charakhandas, rashimanas and ayanamsha.
Astrology is the science which is
based on mathematics and for the purpose of making accurate predictions it is
absolutely essential that the student is conversant with the mathematical
aspects. In fact, it is said that 'Suryasiddhanta' and 'Brihat Jataka'
are two wheels of chariot on which it runs. From this it can concluded that the
equal importance should be given to the mathematical aspect of the science.
Rasimanas
Rasimanas means the rising period of
the sign or rasi. The duration of each sign is a function of latitude of a
place. The average duration of any ascendant is 120 minutes. It is important to know exact duration, because without it the
ascendant cannot be ascertained.
The earth rotates round its axis. During its
rotation, the twelve signs rise and set in their respective order. However, the
rising time of each sign varies. This is because the ecliptic is angular to the
equator. For this , the duration of rasis at the equator are first identified.
This is called as "Lankodaya". (the reason for naming this as
Lankodaya is due to the fact that Sri Lanka is near to the equator). The
duration of rasis at the equator is as follows
Aries,
Virgo, Libra, Pisces 111 min. 36sec
Taurus, Leo, Scorpio, Aquarius 119 min 40sec
Gemini, Cancer, Sagittarius, Capricorn 128 min 44 sec
Taurus, Leo, Scorpio, Aquarius 119 min 40sec
Gemini, Cancer, Sagittarius, Capricorn 128 min 44 sec
Charakhandas
It means that the ascensional
differences. It is the function of latitude and declination. The ascensional
difference is deducted or added from the rashimanas at equator to arrive at the
rasimanas of the defined place. The rasimanas are further used to calculate the
ascendant  one of the important mathematical point for studying horoscope.
Determination
of rashimanas at the given place
The
formula for determining charakhandas for the signs Aries Virgo Libra Pisces is
[19335312*sin(30)*sin(
latitudes of the place ) ]
________________________________________
cos(
latitudes of the place )*60*3365.3581
The
formula for the signs Taurus Leo, Scorpio, Aquarius is
[19335312*sin(60)*sin(
latitudes of the place ) ]
______________________________________
cos(
latitudes of the place )*60*7270.1068
For
the rest of the signs
[19335312*sin(90)*sin(
latitudes of the place ) ]
________________________________________
cos(
latitudes of the place )*60*20151.243
The
answer for the above formula is in minutes.
Let
us calculate the charakhandas for the place at 45N00 latitude(Longitude is not
required since it is the function of latitudes only).
The value of 45N00 latitude
charakhandas for the signs Aries Virgo Libra Pisces is
Sin
(45) = 0.707106
Cos (45) = 0.707106
Cos (45) = 0.707106
[19335312*0.5*sin(
45 ) ]
____________________________
= 47.88 minutes or 47 minutes 53 seconds
cos(
45 )*60*3365.3581
The value of 45N00 latitude charakhandas for the signs Taurus Leo
scorpio aquarius is
Sin(60)=0.866025
Cos(45) = 0.707106
Sin(45) = 0.707106
Cos(45) = 0.707106
Sin(45) = 0.707106
[19335312
* 0.866025 * 0.707106 ]
______________________________
= 38.39 minutes or 38 minutes 23 seconds
0.707106*60*7270.1068
The value of 45N00 latitude charakhandas for the signs Gemini
Cancer Sagittarius capricorn is
Sin(90)= 1
Cos(45) = 0.707106
Sin(45) = 0.707106
Cos(45) = 0.707106
Sin(45) = 0.707106
[19335312*1*0.707106
]
________________________________________
= 16.00 minutes (approximately).
0.707106*60*20151.243
Thus the
charakhandas for 45N00 latitudes are 47.88 minutes for Aries, Virgo, Libra and
Pisces signs, 38.39 minutes for Taurus, Leo, scorpio, aquarius signs and 15.99
minutes for Gemini Cancer Sagittarius capricorn signs.
If the birth is
in northern latitude then the charakhandas thus obtained by the above formulae
be added or subtracted to or from rasimanas at the equator. If the birth is in
northern hemisphere then deduct the charakhandas thus obtained for the
following signs viz. Capricorn, Aquarius, Pisces,
Aries, Taurus and Gemini. The charakhandas calculated for the rest of the signs
be added. If the birth is in the southern hemisphere then the reverse
holds true. Let us calculate rasimanas at 45N00 latitudes.

Ayanamsa
During every
year, the sun has two movements, one towards north called uttarayana and the
other towards south called dakshinayana. During this solar movement the sun
crosses the equator twice in the year; firstly during his northern course and
secondly during his southern course.
When the sun reaches his equinoctial point the duration of day and
night is equal. The year commence at the time at which the sun reaches this
point i.e. 0 degree Aries.
If we consider
the commencement of the year when the sun is in conjunction to the fixed star
and also at the equinoctial point and calculate the year accordingly, it will
be observed that in the subsequent year the sun intersects the equator before
the sun is in conjunction with the fixed star. The difference gets accumulated
every year.
This difference which gets accumulated every year is 50.33 seconds of an arc.
The movement is retrograde i.e. towards west and is called precession of
equinox.
The precession of
equinox is the most important factor not only for mathematical purpose but also
for predictive purpose. It has divided astrology into 2 schools of thought 
a) Sayana System also called as Moving Zodiac (Tropical System)
b) Nirayana System also called as Fixed Zodiac (Sidereal System)
Sayana system includes precession of equinox and horoscope is cast
after including the precession.
Nirayana System however considers the precession for casting of horoscope but the accumulated difference of precession calculated with respect to the fixed point of the zodiac, usually a star, is deducted.
We follow nirayana system since
the Hindus adopted sayana system for mathematical purpose only and it was
reduced to niryana system for predictive purpose.

Just last month I visited our native place and I recollected my childhood because of the things that I saw there. Most of the things are now outdated and our coming generations may not even get to know about them unless we preserve them proudly. We want to take care and preserve all the items mentioned below for coming generations and this blog is just in remembrance of our childhood. I am showcasing a picture below and offering a brief description for those who aren’t aware of the gadgets in the picture. I thought Gudi Padwa is a very good occasion to share this with all of you.

During Diwali poha made from fresh rice on Laath is offered to the god. Laath is also used to grind spices. Above vessel is made from a stem of a large jack fruit tree.

Why Purohit or Priest is not required to perform a Yadnya?
By
Gaurish Borkar

The Vedas have always been presenting
a deeper meaning to every term or action and mostly people fail to understand deeper
meaning of the Vedas. We have been regularly understanding deeper meaning of
many such terms through our blog and books. I could not author a post for a
while due to focus on Untold
Nakshathta Jyotish. All the while I have been thinking about various fundamental
concepts from the Vedas. Untold
Nakshathta Jyotish has many such concepts. Today I plan to explain the concept of Yadnya. Traditionally
when we refer to Yadnya we think of a Yadnya Kunda or a holy pit with fire and Purohits
offering some grains in the holy fire. This is a perfect practice and can be
performed occasionally. The Vedas also suggest PanchaMahaYadnya or 5 key sacrifices
and this practice is supposed to be performed every day. The practice is as below. Everyone
shall perform following Yadnyas every day. 1.Brahma Yadnya Brahma means the universal energy. This Practice is to be performed to

Marathi Kavita: माझा पाऊस
By
Unknown

वाटलं लिहावं काहीतरी कित्ती दिवस झाले मन भरून आलं असे कितीतरी पाऊस गेले
भरून आलं मन तरी ते पावसाबरोबर वाहिलं नाही असे म्हटलं तरी चालेलं कारण पाऊस सोडून, त्याला कोणीच पाहिलं नाही
तो पडतो जेव्हा धोधो तेव्हा काळजाचा ठाव घेतोच आठवणीतलं मनातलं तो आपल्याबरोबर नेतोच
रिमझिम टपटप धोधो आणि सरसर कित्तीतरी रूपं त्याची सारी तशी सुंदर
मला मात्र भावतं त्याचं धोधो पडणं हातच काहीच नं राखता थेट जाऊन भिडणं
त्याच्या येण्याबरोबर जाग्या होतात साऱ्या स्मृती आठवतात काही जोडलेली तर काही पुसट होत गेलेली नाती
वाफाळलेला चहा, कधी सोबत कवितेचं पुस्तक तर कधी नुसत बसून त्याला न्याहाळायचं एकटक
गरम भजी वडा आणि मित्रांसोबत केलेली धमाल तर कधी गाणं ऐकताना त्यावर सहज धरलेला ताल
उडालेली तारांबळ कधी जवळ नव्हती म्हणून छत्री तर आठवणीतली संध्याकाळ कुणासोबातची जवळ एकच होती जेव्हा छत्री
कित्येक क्षण दिलेत त्याने भरभरून जगण्याचे रोजच्या व्यापातून स्वतःला थोडं वेगळ काढून बघण्याचे
काही म्हणा तो आहेच वेगळा नाहीतर असतातच कि हिवाळे अन उन्हाळे पण अनुभव किती हे सांगायलाही म्हणतातच ना " मी पाहिलेत इतके पावसाळे"
