Karthika is one of the 27 birth stars in Indian astrology. It ranks third in the Janma Nakshatra list. This is the birth star of Chandra (Moon). The Devata (god) is Agni. Mangal and Sukra are the lords (Adhipaties) in it.
It is possible to have an idea of the nature of Karthika Nakshatra from the effect of fire (agni). Karthika in Mesha Rashi and Vrishabha Rashi is considered good.
Persons born when the moon was in Karthika Nakshatra are deprived of friends and family; gifted with son and they enjoy a wealthy life. These star holders are stingy, intelligent, famous and successful. They often undertake purposeless traveling and do forbidden jobs.
