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

Adh. I. Sl 10.11] प्रथमोऽध्यायः 5 संहिता-Samhita (compilation or collection). The first स्कन्ध or section where the exact movements, etc., of the planets in the several signs of the zodiac are ascer- tained through mathematical computation is otherwise known as तन्त्र-Tantra. Horoscopy is another section ; अङ्गविनिश्चय-Angavinischaya or locating precisely the cor- rect position of the Lagna, etc., which is the first step in जातककर्म-Jatakakarma is the 3rd. गर्गः गणितं जातकं शाखां यो वेत्ति द्विजपुङ्गवः । त्रिस्कन्धज्ञो विनिर्दिष्टः संहितापारगश्च सः ॥ वक्रानुवक्रास्तमयोदयाद्यास्ताराग्रहाणां करणे मयोक्ताः । होरागतं विस्तरतश्च जन्मयात्राविवाहैः सह पूर्वमुक्तम् ॥१०॥ Sloka 10.—By me have been treated in detail in the करणग्रन्थ (Karana Grantha) पञ्चसिद्धान्तिका (Pancha Siddhanthika), of retrograde and direct motions of the several (non-luminous) planets from Mars onwards, their disappearance (eclipse) through proximity to the Sun, and their reappearance or emerging after conjunction with the Sun, their state of being at war or planetary fight. All things connected with horoscopy along with births, journeys, marriages, etc., have been already treated of in my previous works. This shows that Varahamihira had already written Brihat Jataka, Yatra, etc. प्रश्नप्रतिप्रश्नकथाप्रसङ्गान् स्वल्पोपयोगान् ग्रहसम्भवांश्च । सन्त्यज्य फल्गूनि च सारभूतं भूतार्थमथैः सकलैः प्रवक्ष्ये ॥११॥ Sloka 11.—Omitting queries and their respective answers which are not highly useful for our purpose, and also the origin of the planets and other unessential discussions, I am going to treat of real facts—the quint- essence of everything that is useful.
