The charm, which I have mentioned above, is useful in ensuring that the wearer of this charm is successful in everything that he attempts. However, it would be appropriate to add that that the Gayatri Mantra is a Satvik Mantra [Pure Mantra] and hence will only be useful for unselfis purposes, which do not do injustice to others.
The charm has to be prepared by writing your name on the leaf of a pomegranate tree, using a pointed sandalwood stick, with the paste of Katha [Catechu], a common ingredient, which is widely used in Chewing Paan in India. This leaf should be carefully preserved.
After this, the Gayatri Mantra has to be chanted 1000 times daily for 21 days continuously, the only exception is, if a woman in performing the Sadhana; she should take a break during the Monthly Cycle. On the 21st day after the completion of the 21 day Gayatri Mantra Sadhana, the leaf with the name written on it should be carefully washed with Ganga Jal [Holy Water of the Ganges].
After this, the pomegranate leaf has to be inserted inside a gold locket and worn around the neck, like a good luck charm. The Gayatri Mantra can be seen - Here.
