I made a web based application namely “MS-Longevity”. Before to use, I want to give more details of this method of Satyacharya. Application link given below.
There are some procedures are mentioned to calculate longevity in Varahamihira’s Bruhajjataka , like Manittha, Jiva sarma, Yavana and satyacharya. Among them Satyacharya’s method is preferred by Varaha Mihira , If Asc is strong then only this method will work. ”Saravali” also confirms this statement .If Sun is strong then “Pindayurdaya” will work. If Moon is strong then “Naisrgikaurdaya” should be calculated.
Now I am going to explain Satyacharya’s method and its conditions.
ग्रहभुक्त नवांशराशि तुल्यं बहु साम्यमुपैति सत्य वाक्यम्। BJ-7-9
grahabhukta navāṃśarāśi tulyaṃ bahu sāmyamupaiti satya vākyam|BJ-7-9
Meaning-“According to Satyacharya, the planetary years are the same as the number of
Navamsas passed over by each planet. This view has the support of many authorities.”
Manual method is like this.
सत्यॊक्ते ग्रहमिष्टं लिप्तीकृत्वा शतद्वयॆनाप्तः।
मण्डलभाग विशुद्धॆऽब्दास्युः शॆषात्तु मासाद्याः॥ BJ-7-10
satyokte grahamiṣṭaṃ liptīkṛtvā śatadvayenāptaḥ|
maṇḍalabhāga viśuddhe:’bdāsyuḥ śeṣāttu māsādyāḥ|| BJ-7-10
Meaning- “According to Satyacharya, convert the Sphuta or longitudes of the planet degrees into minutes; divide the number of by 200; the quotient will represent the number of Navamsas passed over by the planet from the first point of sign. The remainder will give the number of years ?.
Now I explain with clarity to get months and days etc….
Step-1; Take the degrees of planet and convert them into minutes , then divide by 200, quotient will be the years and remainder should be multiplied by with 12 and again divide by 200 then that quotient will be the months, then remainder should be multiplied by 30 and again divide by 200 the quotient will be the days, then remainder should be multiplied by 60 and again divide by 200 the quotient will be the hours, again
remainder should be multiplied by 60 and gain divide by 200 the quotient will be the minutes This is the process of 1 to 30 degrees.
Like this minutes multiplied by 60 and divide by 200 you should get hours in quotient , again remainder should multiplied by 60 and divide by 200 you get minutes, lastly remainder multiply with again 60 and divide by 200 seconds will be arrived.
According the planets degree and minutes longevity can be calculated. First calculate the longevity years –months –days, of Sun to sat planets. After that gross longevity will be arrived. Next we have to do some adding and subtracting according to the planets positional status.
स्वतुंगवक्त्रॊपगतैः त्रि संगुणम्द्विरुत्तम स्वांश गृह त्रिभागगैः।
इयान् विशॆषस्तु भदन्तभाषितॆ समानमन्यत् प्रथमॆऽप्युदीरितम्॥ BJ-7-11
svatuṃgavaktropagataiḥ tri saṃguṇamdviruttama svāṃśa gṛha tribhāgagaiḥ|
iyān viśeṣastu bhadantabhāṣite samānamanyat prathame:’pyudīritam|| BJ-7-11
Meaning in point wise as follows-
1-If planet in exaltation or in retrogration then multiplies the longevity by 3.
2-If planet in Vargottama or in own Navamsa or in own House or in own Drekkana then double the longevity.
This called as Bharana [Adding].
3-If planet in debilitation or in combustion within the 8o to Sun then divide by 2 .
This condition would not apply to Sat and Venus.
4-If planet in enemy’s House then subtract 1/3 part of the longevity
This is called as Harana [Subtracting].
At this level the native will get actual longevity given by planets.
Tripling the years of retrograded planet is a special feature in Satyachary’s longevity. In other respects, it resembles the Pindayu1daya rules , but the reduction known as Chakrapatha Harana and krurodaya harana does not apply to Satyacharya’s method. According to Satyacharya the years, months, for the Lagna, the rising degree, are the same as the number of Navamsaa passed over.
आयुर्दायं विष्णुगुप्तॊऽपि चैवं दॆवस्वामी सिद्धसॆनश्च चक्रॆ ।
दॊषश्चैषां जायतॆऽष्टावरिष्टं हित्वा नायुर्विंशतॆः स्यादधस्तात् ॥ BJ; 7-7
āyurdāyaṃ viṣṇugupto:’pi caivaṃ devasvāmī siddhasenaśca cakre |
doṣaścaiṣāṃ jāyate:’ṣṭāvariṣṭaṃ hitvā nāyurviṃśateḥ syādadhastāt || BJ; 7-7
Varahamihira mentioned some other methods of 1-Maya,2-Yavana,3-Manittha,
4-VishnuGupata;5-Deva Swami; and 6-Siddha Sena. Here Varahamihira criticized as those other methods are not applicable due to errors.
Above verse meaning is, “according to these methods death will not happen in between ages from 8 to 20 years” .But practically the same is not holding true. Varahamihira vehemently criticized all methods from Maya to Siddhasena and praised Satyacharya’s theory twice.
Some were thought as these two verses 7 and 8 are interpolated by some others,
But commentator Bhattotpala thinks that these verses are not of others though objection to Pindayurdaya raised in it ,he meets follows by proving that Pindayurdaya does give below 20. He took one example horoscope and discussed in lengthy,
सत्यॊपदॆशं वरमत्र किन्तु कुर्वन्त्ययॊग्यं बहु वर्गणाभिः।
आचार्यकं त्वत्र बहुघ्नतायाः एकं तु यद् भूरि तदॆव कार्यम् ।।BJ-7-13
satyopadeśaṃ varamatra kintu kurvantyayogyaṃ bahu vargaṇābhiḥ|
ācāryakaṃ tvatra bahughnatāyāḥ ekaṃ tu yad bhūri tadeva kāryam ||BJ-7-13
Meaning- “In the matter of Ayurdaya, the method of SatyaCharya is the best. Objection is made to it on the ground that the planetary years have to be multiplied several times. This is wrong; where any period has to be multiplied by several numbers, it will be sufficient if the period is multiplied by the larger number”.
Suppose Mercury to occupy sign Virgo which is his exaltation sign as well as his house. It would seem that under verse 2, Mercury’s years should first be trebled and then doubled. Is this to be done again, suppose Mercury to occupy the last Navamsa.
Of sign Virgo which is his Vargotama position. His years, it would appear, have to be doubled on that account. Already we found that for being in his house, his years had to
be doubled. The question is whether the years of Mercury have to be doubled twice. Again, suppose Mercury while occupying Virgo, his exaltation sign, is also retrograde in
his motion for which his years have to be trebled. Are his years then to be trebled twice? No.
Bhattotpala elaborated this issue in his commentary as like with these lines of ancients verse.
विलग्नभॆ बलोपॆते सुभदृष्टॆंऽशसंभवः रवौ पिण्डॊद्भवं कुर्यादितिबॄयाच्चिरन्तनाः॥
vilagnabhe balopete subhadṛṣṭeṃ:’śasaṃbhavaḥ ravau piṇḍodbhavaṃ kuryāditibrUyāccirantanāḥ||
Meaning- Manitha and others ancients sages are told as “If Asc is strong then follow the Satyacharya method, if Sun is strong then follow the Pindayurdaya method of Manitha and others.
Some commentators are amended this as ,do both calculations of 1-Pindayurdaya and 2-Amsayurdaya of Satyacharya ,after that take which is less and then in that less period see the last Dasa lord ,if he is friend of starting Mula Dasa lord then that native will complete that Dasa and live after that one. If he is enemy then death take place if he is neutral then some sever health problems take place .
Ammendment-1 ; If planets are in mutual exchange , then :Double:the longevity of highest one and remaining should be as it is.[ This rule proved many charts]
Ammendment-2 ; If Asc lord aspects Asc from any friendly house then according to his strength 4 to9 years should be added . Because the longevity of seven planets are given but Asc had not mentioned in scripture, in Ashtakavaraga also have some Bindus for Asc also , so it also useful to get accurate longevity.
Ammendment-3 ; If Asc is devoid of any malefic planet and contains natural benifics
Like Jupiter ,Venus, Moon ,then 3 years should be added.[This rule proved many charts]
1-Condition of Streangth; If Ascendant is stronger than Sun and Moon then only this method works perfectly.
2-Condition of Ayanamsa; ”Surya Siddhanta” Ayanamsa only should be followed for longitudinal positions of the planets, because, in ancient time the exponent Satyacharya and Varahamihira were followed ”Surya Siddhanta” only.
Now I am going to explain some examples, followed by “Surya Siddhanta “ Ayanamsa.

According to the planet degrees below mentioned gross level longevity has arrived,
Now I did additions and subtractions according to the positional status of the planets.
Sun and Mercury in mutual exchange ,so Mercury doubled, Moon in enemy house so 1/3 subtracted, Jupiter and Sat are retrograded so both are tripled, Venus in own house so doubled .Then actual longevity arrived, then added to DOB.
Long= 61-07-17 ; 1966-5-19; Actually sastry died in 1966-01-11; only 4 months deference.
Case-4 ; Princes Diana; 1981-7-1; Time-20-18;Semdringham.
Moon in enemy house so 1/3 subtraction. Mercury , Jupiter, Sat are are retrograded so they are tripled, Venus in own house so doubled .Then actual longevity arrived . Here Mercury is combusted , so we have to subtract manually half of the given longevity, then it will be 5yrs-22days and 12 hrs , subtract this from 37-4-29.then it will be 32-4-6 .As per amended rule we have to add 4 more years ,then 36-4-6.
Longevity = 36-4-6; 1997-11-7.Diana died on 1997-8-31. 2 months 8 days are deference.
Ancient methods are accuracy oriented ,but some links and parameters are missed.
So we have to reorient this Satyacharya’s method and get benefit .Astro researchers are requested to test this method vigorously ,if need any adding and editing rules to this application ,then it will be modified into a practical one.
