GLOSSARY Inducca () Moon's apogee, i.e., the remotest point of the Moon's orbit. Indriya (fa) Five. Indvahah () Lunar day or tithi. Isu () Five. Ista (2) Given, or desired, or chosen at pleasure. Ucca () The ucca is the apex of a planet's orbit. It is of two kinds: (1) mandocca, i.e., the of apex slow motion, and (2) sighrocca, i.e., the apex of fast motion. In Hindu astronomy, the mandocca is defined to be the remo- test point of the planet's orbit where the planet appears smallest¹. It is therefore the same as the "apogee" of modern astro- nomy. The sighrocca of the superior planets is an imagi- nary body which remains in the same direction as the mean Sun; that of an in- ferior planet lies approxi- mately in the same direction from the Earth as the actual planet is from the Sun. 235 Uccabhukti (उच्चभुक्ति ) (Daily) motion of the ucca; apsidal motion.
