Grahamātṛkādhāraṇī

A Buddhist Dhāraṇī text contains mystic mantras for the veneration of the nine planets. These mantras belong to the Tantric class. The text describes the rituals of worshiping the planets with diagrams drawn on the floor of a room, chanting the mantras seven times each day, from the seventh day to the 14th day of the waxing moon in Kartika, with the final ritual occurring at midnight on the 15th day. The mantras were revealed to a congregation of gods by Buddha himself while residing in the Alakavati mansion of Indra (Mitra, 1882, pp. 50-51). This dhāraṇī also forms a part of the saptavāra tradition, and is said to preside over Saturday. (Gudrun Bühnemann, A dhāraṇī for each day of the week).
