Vashistha
Vashishtha (Sanskrit: वशिष्ठ, वसिष्ठ, IAST: Vaśiṣṭha, Vasiṣṭha, Thai: Vasit, Tamil: வசிட்டர்) is one of the Saptarishis (seven great Rishis) in the seventh, i.e. the present Manvantara, or age of Manu. Vashista is a manasputra of God Brahma. He had in his possession the divine cow Kamadhenu, and Nandini her child, who could grant anything to their owners. Arundhati is the name of the wife of Vashista. RigVeda 7:33 mentions Vashishtha rishi as son of MitraVaruṇa and Urvasi.
Vashistha, as one of 9 Prajapatis, is credited as the chief author of Mandala 7 of the Rigveda. Vashistha and his family are glorified in RV 7.33, extolling their role in the Battle of the Ten Kings, making him the only mortal besides Bhava to have a Rigvedic hymn dedicated to him. Another treatise attributed to him is "Vashistha Samhita" – a book on the Vedic system of electional astrology.
Arundhati and Maharishi Vashistha pair of stars
Mizar is known as Vashistha and Alcor is known as Arundhati in traditional Indian astronomy. The pair is considered to symbolise marriage (Maharishi Vashistha and Arundhati were a married couple) and, in some Hindu communities, priests conducting a wedding ceremony allude to or point out the constellation as a symbol of the closeness marriage brings to a couple. Since Vasishta was married to Arundhati, he was also called Arundhati Natha, meaning the husband of Arundhati.
