Mahadevi, known as the Great Goddess, is represented by various names and forms in Jyotish, which is the Vedic science of astrology. Her impact spans from universal influence to specific connections with celestial bodies, zodiac signs, Nakshatras, and lunar phases. In Hindu philosophy, she is regarded as the Mother of the Universe, the source of creation, sustenance, and dissolution of all things. She oversees the entirety of time—encompassing the past, present, and future—and all dimensions of space.

As the Supreme Mother, the Goddess transcends the confines of any one planet, zodiac sign, or astrological marker. Her influence manifests across multiple levels and dimensions, permeating all universal forces that are expressions of her Supreme Shakti. She embodies every aspect of femininity and encapsulates the creative and life-giving energies of light. Additionally, she exists beyond form, reaching into the fundamental essence of time and space. We will delve into her principal astrological representations.

Historically, the Moon has been recognized globally, particularly in traditional societies, as the foremost representation of the Goddess. This is equally applicable in Vedic astrology, where the Moon symbolizes the face and smile of the Universal Mother, bestowing grace, tranquility, inspiration, insight, and joy. When we observe the Moon, we are connecting with her essence and absorbing her subtle energies. Vedic astrology acknowledges various aspects of the Goddess based on her position in the zodiac and the lunar cycle, with numerous poets and sages celebrating the Divine Mother and the Moon, especially in her incarnation as Uma.

The Moon is governed by the force known as the Cosmic Waters (Apas), which is another aspect of the Goddess. Uma Parvati, the consort of Shiva, is recognized as the principal deity (pratyadhi-devata) associated with the Moon. The name Parvati also signifies the concept of parts, reflecting the different phases and transformations of the Moon. As the Goddess of nature and the wild, she embodies the spirit of yogic ascetics, serving as the supreme Yogini and Yoga Shakti who guides us toward the transcendent Shiva.

Interestingly, in the ancient hymn from the Rigveda concerning the union of the Sun and Moon (RV X.85), the Goddess is depicted as the Sun, while the Moon is portrayed as her male admirer orbiting around her. Known as Surya Savitri, the Goddess represents the solar knowledge power (Surya). She is associated with the veneration of the Sun during sunrise (Gayatri), noon (Savitri), and sunset (Sarasvati), which are three transitional phases known as Sandhyas, with Sandhya also being an incarnation of the Goddess. As Ushas, she personifies Dawn in the Vedas, while as Aditi, she is the Universal Mother who births all the Sun Gods (Adityas). Other Hindu Goddesses linked to the Moon may also connect with the Sun, such as Ma Durga, who rides the solar lion.
