On the night of Purnima, if desirous of performing this ritual one has to have a bath, wear clean and fresh clothes. Then looking at the Moon, the Gayatri Mantra has to be chanted 12 times and then you have to go to sleep. After chanting the mantra one must not speak to anyone; if this is done by mistake, then you have to chant the mantra 12 times again and then go to bed.
This simple Sadhana is said to make sure that you do not face any financial problems throughout the month. If you get some relief then you can repeat it on all Purnimas.
