This is a Shri Ram Yantra; a good luck Yantra to have the blessings of Shri. Ram. This good luck charm will be most fruitful for the devotees of the Maryada Purushottam, who like fair play in all their dealings and are Satvik in temperament.
The procedure for making the Yantra is easy – Write it on a blank white piece of paper with red ink, like show in the diagram. Then you can show some Dhoop to the Yantra and chant any Shri Ram Mantra you like 11 times. You can find some here in this section – Ram Mantras
Then keep fold it and keep it in your pocket or purse. The meaning of the words inscribed in the Yantra is “Help me Shri Ram”
When the Yantra gets spoiled, immerse it in a water body and repeat the entire procedure to get a new Yantra.
