Mangalwar Vrata (For acquiring courage and power to win over enemies).
The deity of this fast is Mangal (Mars) who is God of power, war and courage. He eradicates fear and enemies. By doing this fast poverty gets eradicated. Problems like blood pressure get cured. All worldly desires get gratified like gain of son, wealth, religion, fulfillment of wishes and also favour of government. By doing it continuously for 21 weeks one gets rid of all Mars related problems. Mangalwar (Tuesday) is considered the birth day of Lord Hanuman, therefore, one who performs this fast gets protection from Hanuman. And gets rid of physical, supernatural or worldly troubles. This results in intellectual development and attainment of physical strength or stamina.
