16. I have explained lost horoscopic rules, as expounded by Yavana, Bhadasana etc. But some of their rules are ambiguous. The student better understand using his judgement.

17-21. LOST HOROSCOPY BASED ON MOON. Just as the ascending degree helps trace back the lost details, the Moon Sign may also be used. If the Moon Sign at the time of query be a night Sign, natal Moon was in a day Sign and vice versa. Note in what quarter of the Sign is the Moon at the time of query. Proportionately understand the natal Moon during day, or night, as the case may be. Multiply the query Moon by the same Rasi multiplication factor, as explained supra and, if necessary by planetary multipliers, as applicable. Multiply the resultant product (arrived by adding the two) by 7 and divide by 27. The remainder will represent the birth star counted from Aswini. In case of rectification by adding 9 the counting is from Moola and, if subtraction of 9 is done count from Makha. The pre-division product (i.e. the product before dividing by 27, as above) should be processed variously, as suggested earlier to know the Ritu, month, Tithi etc. at birth.
