In astrology, a Graha is a celestial body that is believed to have an influence on the lives of people. There are nine Grahas, which are the Sun, the Moon, Mars, Mercury, Jupiter, Saturn, Rahu, and Ketu. Each Graha is associated with a particular aspect of human life, such as health, wealth, relationships, and so forth.
The Sun is said to represent the soul, while the Moon signifies the mind. Mars is associated with energy and aggression, while Mercury is thought to represent communication and intellect. Jupiter is considered to be the planet of luck and fortune, while Saturn is linked with discipline and hard work. Rahu is associated with change and transformation, while Ketu is linked with spirituality and introspection.
The placement of the Grahas in a person's birth chart is said to indicate the areas of life that will be most affected by them. For example, if the Sun is strong in a person's chart, then they are likely to have a strong sense of self and be confident in their abilities. If the Moon is strong, then it may be more emotional and sensitive. If Mars is strong, then it may be more dynamic and active.
Each person is said to have a ruling Graha, which is the Graha that has the most influence over them. This can be determined by looking at the position of the Grahas in a person's birth chart. The ruling Graha is said to represent the core of a person's personality and can give insight into their strengths and weaknesses.
