Donate a cat's eye gemstone, a brown cow with white spots, colored blankets or black mustard seeds on Thursday or a dog to a poor young man on Thursday.
Reciting of Shiva Panchakshari Stotra.
Worshipping Lord Ganesh.
Keeping a fast on the first Thursday of the waxing moon.
Chanting the Ketu Mantras 18000 times on 108 japa beads and performing puja with mixed flowers and sandal wood within the ascending cycle of the Moon.
