बृहत्संहिता (आचार्य वराहमिहिर - स्थापत्य, खगोल, मौसम व जल विज्ञान)

Adh. VIII. Sl. 20.-22] अष्टमोऽध्यायः 95
क्रूरग्रहेहते देहे दुर्भिक्षानलमारुताः ।
क्षुद्भयं तु भवेन्नाभ्यां पुष्पे मूलफलक्षयः ॥
हृदये सस्यहानिः स्यात्सौम्यैः पुष्टिः प्रकीर्तिता ।
गतानि वर्षाणि शकेन्द्रकालाद्धतानि रुद्रैर्गुणयेच्चतुर्भिः ।
नवाष्टपञ्चाष्ट युतानि कृत्वा विभाजयेच्छून्यशरागररामैः ॥२०॥
लब्धेन युक्तं शकभूपकालं संशोध्य षष्ट्या विषयैर्विभज्य ।
युगानि नारायणपूर्वकाणि लब्धानि शेषाः क्रमशः समाः स्युः ॥२१॥
Slokas 20-21.—Find out the number of years that
have elapsed since the commencement of the Salivahana
era. Multiply this by 44. Add 8589 to the product and
divide the result by 3750. To the quotient thus obtained,
add the Saka years. Divide this by 60 and the remain-
der thereof by 5. The quotient represents the five-year-
periods ruled by Vishnu and others, and the remainder
denotes the number of years that have elapsed in the
particular lustrum.
एकैकमब्देषु नवाहतेषु दत्त्वा पृथग्द्वादशकं क्रमेण ।
हृत्वा चतुर्भिर्वसुदेवताद्यान्युडूनि शेषांशकपूर्वमब्दम् ॥२२॥
Sloka 22.—Place the years of Jupiter obtained in the
previous Sloka separately in two places. Multiply the
first by 9 and divide the other by 12. Add the above
product (in the first case) and the quotient (in the second
case). Divide the result by 4. The quotient will reveal
the particular asterism reckoned from Dhanishta. The
remainder will denote the Padas (पाद) in the next star
that have been traversed by Jupiter.
In a Mahayuga (the period comprising the four Yugas),
the number of solar years is 4320000 = 3750 × 1152 * 4370640
That of Jupiter for the same period is as per Surya
4370688* = 3794 × 1152 Siddhanta.
