Here’s a short video to explain the terms ucca (उच्च) and nīca (नीच), which, in astrology, refer to “exaltation” and “debilitation.”
Ucca literally means raised up, and nīca literally mean’s to fall low. And, actually, that’s what the terms “exaltation” and “debilitation” also mean. Exalt means to raise up, and debilitate means to bring low and weaken.
These are terms about dignity. The basic principle is that if you have “high” dignity, you behave well. A “dignified” person behaves well. An “undignified” person behaves poorly. And what is the cause for this behavior? It’s whether or not you feel happy and satisfied. This is an important principle in yoga, philosophy, and psychology. If you feel happy you tend to act nicely. If you feel miserable you tend to act nasty.
When planets get into situations that make them feel depressed (nīca also means “depressed” – pressed down), they become snappy, bite-y, and do nastier things. So the nastier implications of their potential interpretations come out. And, the higher their dignity (the more “ucca”) the more happy and satisfied they feel, and when you feel happy and satisfied you don’t lash out, you have a lot more patience and are a lot more generous in your behavior. So, planets which are “ucca” will give better permutations of what they could possibly represent.
PS: Please remember that dignity is NOT determined solely by the rāśī sign! It is a combination of all the varga signs, and is also influenced by other factors like aspects and conjunctions. Those who say “dignity is not a useful technique” probably just don’t know this (or may not be using an accurate zodiac system).
