Brihat Samhita
युद्धं यथा यदा वा भविष्यम् आदिश्यते त्रिकालज्ञैः । तद्विज्ञानं करणे मया कृतं सूर्य सिद्धान्ते ॥ १७-०१ ॥
Astronomers are able to predict by calculation beforehand the time and nature of planetary conjunctions (grahayuddha). I have treated of this subject in my astronomical work, Pañcasiddhāntikā basing my theories on the Sūrya Siddhānta.
