The ārūḍha pada of a planet is called graha pada. It is exactly like the reflection of an object which, in this case, is the planet itself. Every planet has an image or a place where its reflection falls. This reflection is about the sign it owns like svakṣetra (own sign) or mūlatrikoṇa (office, work). Just as we calculated bhāva pada, we also calculate the graha pada.
