Ketu is believed to be the repository of past and present karmas and is associated with a variety of significations in astrology, including asceticism, assassinations, contemplation, desire for knowledge, deep thinking, imprisonment, poison, intrigues, magical powers, poverty, mysticism, and spiritualism. It is believed that the part of the body associated with the house where Ketu is in a birth chart may have a birthmark, such as a burn mark, cut, or black spot. The individual may also experience irritation or pain in that part of the body.

Ketu is also known for his ability to curtail the qualities of the planets that come into contact with him, either for good or for ill. He is seen as a powerful and unpredictable force that can bring great success or great failure to those under his influence. Ketu is associated with detachment and damages to the significations of house with which it is related. It can give growth to person to rise to level of King but still will detach from few of the important issues of life. It can also bring negative consequences, such as poverty, failure, and physical or mental disability. Ketu is the hidden energy related to Muladhara Chakra and its energies are hidden, mysterious and fructify as per past life deeds of a person.

Ketu is also known as Dhwajah, or the flag, and is associated with power and authority. Those with a strong Ketu placement may be blessed with positions of power and authority, but they may also face allegations of corruption, malpractice, and bribery. In cases where these allegations are false, it is believed that the individual can seek protection by placing a large flag on the top of a temple, particularly a Ganesha or Hanuman temple.

Ketu is believed to be a powerful force that can cause significant obstacles and challenges in an individual's life path. It is associated with pain, change, and the need to leave behind excess baggage from past karmas. It may also divert the individual towards Rahu, which represents the future and the need to address certain areas of life. While Ketu brings detachment, Rahu brings attachment and encourages the individual to learn new things and break away from conventional ways of thinking. It can be difficult to stand in the way of Ketu's power, as it is working to bring enlightenment and understanding of the divine plan, which is an integral part of one's destiny. Ultimately, the goal is to achieve true enlightenment and honor through the process of enlightenment brought on by Ketu.
