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

28 PAÑCASIDDHĀNTIKĀ II.4 nothing is said, then the emendation gatikāṣṭhāṃśa is the proper one, which we have given. (TS also give this). If, on the other hand, we take it that the instruction is to subtract 2 minutes per ghana, taking the word projjhya in the previous instruction to be understood here also, then the emenda- tion gatyaṣṭāṃsa will be the proper one. In this case we would also have to keep the letter ṭa of the original as it is, without changing it into ṭha. But the addition of 2 minutes per ghana alone would agree with the correct mean motion for the period of our author which is in cycles etc. 110-11-7-32- 15 for 3031 days, the Vāsiṣṭha mean motion being 110-11-7-32. NP have emended the word as ṣaṣṭhāṃsa which would not give the correct result. *Example 2. Find the mean Moon for the end of the gati just before Days from Epoch, 3,0
