[The natal Ayana, other natal factors, position of the querist, personal name, another method, lost horoscopy based on the Moon at query]

1. THE NATAL AYANA. If the Ascendant at the time of query (related to tracing the lost birth data) be within the first 15 of a Sign, the birth was in Uttarayana and beyond these degrees Dakshinayana.

2-3. BIRTH RITU ETC. The strongest of the planets in the Prashna Lagna indicates the Ritu (season) at birth. Should there be none in the Ascendant, the Lord of the ascendental decanate is the ruler of Ritu at birth. Should there be a clash in the Ayana and Ritu arrived at, the Ritu Lords arrived should be interchanged thus: the Moon for Venus, Mercury for Mars and Jupiter for Saturn. The respective month of the Ritu is decided depending on the first, or second half of the decanate being Ascendant. The degrees elapsed in the decanate will be to the knowledge of the natal Tithi. Some say, that this will lead to locating the natal Sun.

4-9. OTHER NATAL FACTORS. The query Ascendant be multiplied by 2 and divided by 5 to get the natal Jupiter's placement. This should be adjusted to actual placement guessing the native's age approximately, by increasing, or decreasing multiples of 12. If the query Ascendant is in a day Sign, declare birth during night. Otherwise, the contrary prevails. The degree elapsed in the query Ascendant will lead to the knowledge of elapsed portion of night, or day, as the case may be. Out of the query Ascendant, the 5^th and the 9^th therefrom will indicate the natal Rasi (Moon Sign), the strongest of the three prevailing. The parts of the body, viz. head etc. touched by the querist at the time of query will also indicate the Moon Sign at birth. Alternatively the distance between the query Ascendant and the query Moon may be added to the query Moon to get the position of the natal Moon. This does not apply to the Moon in Pisces at the time of query, (i. e. the natal Moon is in Pisces itself). The Navansa Lagna at the time of query may also be the natal Ascendant. The number of decanates between the query Ascendant and query Sun, when added to the query Sun, will yield the natal Ascendant. The longitude of the planet in the query Ascendant should be multiplied by the figure indicated by Chayangula (length of shadow) at that time. This should be divided by 12, the remainder of which will indicate natal Ascendant.
