Sphujidhvaja begins (YJ 52, 1–5) with rules for reconstructing the lost horoscope of the nativity of the client from the horoscope of the time of his query; this topic, entitled \*naṣṭajātaka\*, was normally dealt with in later \*jātaka\* texts. Thereafter he discusses methods of determining the subject of the querist's question before he puts it (YJ 52, 7–10, and 53–62); in part he uses the pharmacological categories of \*āyurveda\* (YJ 62) associated with celestial bodies. The following \*adhyāya\* (YJ 63) answers the question of whether what the querist is thinking of will in fact occur; and then there come discussions of lost or stolen objects (YJ 64), of sickness and death (YJ 65), of the sex of unborn or unseen children (YJ 66), of dinner (YJ 69–70). The final two \*adhyāyas\* in this section (YJ 71–72) give elaborate rules for reconstructing names from astrological phenomena. - [Previous: c9.2](https://indike.org/pramana/ins.science.pingree-1981.c9.2) - [Next: c9.4](https://indike.org/pramana/ins.science.pingree-1981.c9.4) - [Up: c9](https://indike.org/pramana/ins.science.pingree-1981.c9) ## Linked texts (1) - [Vṛddhayavanajātaka](https://indike.org/pramana/in.astro.hora.yavana.vrddhayavanajataka) — Mīnarāja, Sanskrit --- Source: [https://indike.org/pramana/ins.science.pingree-1981.c9.3](https://indike.org/pramana/ins.science.pingree-1981.c9.3) · Pramāṇa
