पञ्चसिद्धान्तिका (आचार्य वराहमिहिर - सूर्य, रोमक, पौलिश, वासिष्ठ एवं पितामह सिद्धान्त)

356 PAÑCASIDDHĀNTIKĀ XVIII.66 65. In eighteen āryā verses, Varāhamihira, without feeling any jealousy, gives this manual to the world, ending with the treatment of the planets, thinking that it is good. Note 1. The emendations are TS's also. Note 2. Verse 64 is a paranomasia and means also, "Salutation to the good science of astronomy called technically parahita-gaṇita (prevalent in Kerala in South India), which at the beginning deals only with mean motions, though knowing its defective nature as not being true motions, and which furnishes tabular values of equations going by the means, mandajyā (R sine table of the equation of the centre), karkijyā (R sine table of the equation of conjunction for the anomaly 90° to 270°) and makarajyā (R sine table of the equation of conjunction for the anomaly 270° to 90°)." This meaning being not obvious to the ordinary reader, I give the phrase by phrase meaning: prastāve (granthārambhe), parokṣasya (asphuṭagrahasya) doṣān (asphuṭatvādi-doṣān) jānann api yaḥ na vakti (jānann api na vadati, madhyagater eva prakṛtatvāt) guṇān (mandajyā, karkijyā, makarajyā ityādi- guṇaśabda-vācyā jyāḥ) prathayati (prakaṭīkaroti, gaṇayitvā likhatīti yāvat), tasmai sujanāya (tasmai śobhanajanmane) parahitāya (parahitagaṇitāya) namaḥ (namo 'stu). Note 3. These two verses also form part of the 18 verses mentioned. So, actually there are only 16 verses (66 to 81), giving the computation. [सौरदिनम्] आकरणाद् रविभागा दिवसा (श्रा) रंशका रवौ कार्याः । अधिका (य) दा दि(ने) भ्यो भागा ज्ञेयास्तदा चक्रात् ॥ ६६ ॥ ‘Sun’s day’ (Sauradina) 66. From the epoch, to the time of computation of the planet, find the Sun’s degrees passed. These are to be technically called ‘days’, (and used in the com- putation). Find the remainder after dividing by the cycle number given for the respective star-planet. Take the ‘days’ of motion corresponding to the set of motions given to the respective planet. These are degrees of planetary motion. Add this to the Sun's longitude. The true planet is got. Note 1. The ‘days’ mentioned here is only what is called sauradina (‘Sun’s day’) as distinguished from the sāvana or civil day, and are actually degrees. (This is like the word ‘light-year’, which is used as a unit of distance). This instruction is given with respect to all planets. 64a. A.B. दोषाः c. A. वराहमिह वराहमिहिरो (A2. ०म्पितिहरो); b.
