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

Adh. V. Sl. 14-17] पंचमोऽध्यायः '49 योऽसावसुरो राहुस्तस्य वरो ब्रह्मणाऽयमाज्ञप्तः । आप्यायनमुपरागे दत्तहुतांशेन ते भविता ॥१४॥ तस्मिन् काले सान्निध्यमस्य तेनोपचर्यते राहुः । याम्योत्तरा शशिगतिर्गणितेऽप्युपचर्यते तेन ॥१५॥ Slokas 14-15. The following boon has been con- ferred by Brahman on Rahu, the Demon : "You shall have to live and rest satisfied with whatever gifts and oblations that may be given at the time of an eclipse." During that period his presence is recognised. There are two places or nodes for the Moon caused by her deviation south or north and this is ascertained by astronomical calculation. The ascending node is termed Rahu. न कथञ्चिदपि निमित्तैर्ग्रहणं विज्ञायते निमित्तानि । अन्यास्मन्नपि काले भवन्त्यथोत्पातरूपाणि ॥१६॥ Sloka 16.—An eclipse can by no means be ascer- tained through symptoms in the form of portents. For, these latter, viz., fall of meteors, etc., occur at other times also. पञ्चग्रहसंयोगाच्च किल ग्रहणस्य संभवो भवति । तैलं च जलेऽष्टम्यां न विचिन्त्यमिदं विपश्चिद्भिः ॥१७॥ Sloka 17.—It is not correct to say that an eclipse cannot occur unless five planets combine; it is also incorrect for the learned to suppose that on the previous Ashtami day the eclipse and its characteristics can be guessed by examining the appearance of a drop of oil poured on the surface of water. तथा च वृद्धगर्गः । इह पञ्चार्कसंयोगं दृष्ट्वा न ग्रहणं वदेत् । यदि न साशुक्रस्तत्र सं दृष्ट्वा ग्रहणं वदेत् ॥ बृ. सं. 7
