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

22 बृहत्संहितायाम् [Adh. III. Sl. 1-4 आदित्यचारः ॥३॥ The Sun. आश्लेषार्द्धाद्दक्षिणमुत्तरमयनं रवेर्धनिष्ठाद्यम् । नूनं कदाचिदासीद्येनोक्तं पूर्वशास्त्रेषु ॥१॥ Sloka 1.—The Sun’s southern course began at one time from the latter half of Aslesha and the northern, from the beginning of Dhanishta. This must indeed have been the case as it is so recorded in our ancient Sastras. साम्प्रतमयनं सवितुः कर्कटकाद्यं मृगादितश्चान्यत् । उक्ताभावो विकृतिः प्रत्यक्षपरीक्षणैर्व्यक्तिः ॥२॥ दूरस्थचिह्नवेधादुदयेऽस्तमयेऽपि वा सहस्रांशोः । छायाप्रवेशनिर्गमचिह्नैर्वा मण्डले महति । ३॥ Slokas 2-3.—At present, one course of the Sun begins from the commencement of Karkataka and the other from the beginning of Makara. That it is different from what has been stated above can easily be ascertained by direct observation. By marking every day the position of an object situ- ated at a distance at the time of the rising or setting of the Sun, or watching the entry and exit of the brim of the shadow of a stick placed at the centre of a big circle drawn on the Earth, the difference in the Sun’s course may be detected. अप्राप्य मकरमर्को विनिवृत्तो हन्ति सापरां याम्याम् । कर्कटकमसम्प्राप्तो विनिवृत्तश्चोत्तरां सैन्द्रीम् ॥४॥ Sloka 4.—When the Sun retraces his steps before he has reached Makara and changes his direction, he destroys the West and the South. When he similarly changes his course without reaching Karkataka, he brings evil to the North and the East.
