Take the Janma Lagna Patrika and start counting the numbers from the Ascendant [Lagna] till the House in which Mars is positioned. Then add to this the number of the Rashi[ the House in which Moon is located].
For example if your Ascendant[Lagna or First House is Pisces and Mars is located in the Seventh House of Virgo, then your number will be 7 and if Moon is located in the 11th House of Capricorn, then your Rashi will be Capricorn and the number will be 11. By adding 7 and 11, you will arrive at a total number of 18.
Now for the remedy, purchase a new red colored handkerchief and some Batasas [Indian Sugar Candy, widely used in Puja-Archana].
Place exactly the same number of Batasas in the middle of the handkerchief as the total number you have arrived at. Then worship the Batasas by offering Agarbatti, Diya and scented flowers.
Then tie the handkerchief with Battasas, like a bundle and immerse them in a flowing water body, like a river.
This remedy should be practiced once a year, doing this will remove the malefic effects of Mars and with it the hurdles, problem and delays in getting married.
