Om Shri Mangalaya Namaha A person desirous of strengthening Shri Mangal Graha Devata can chant any of His associated mantras. 108 times every Mangalvaar facing South. Prithvi is the Adi devata of Mangal graha and a simple loving remembrance of Hers as Om Prithvi Devyai Namaha would be beneficial Worship of Anjani Putra Hanuman and Parvati Putr Karthik are both very beneficial during Mangalvaar Donating red clothes / blankets to the poor and needy on Mangalvaar is very good. Thanks
