When Mars is placed in Uttara Ashadha nakshatra, it can give the native a highly competitive and ambitious nature. Uttara Ashadha nakshatra is governed by the Vishwa Devas, or universal gods, which gives it a highly spiritual and ethical essence. The combination of Mars in this nakshatra can give rise to a warrior-like personality that is dedicated to achieving greatness through determined striving and hard work. However, misusing the energy of Mars in an unethical way can result in negative consequences.
