The Gayatri Mantra
The Gayatri mantra is a popular Vedic mantra. Gayatri is the mythical goddess of dawn. She represents the Sun as it rises. This mantra is a supplication to God to help us in our life. The Gayatri mantra is described in the Vedas to be used in a ceremony called the sandhya vandanam. Sandhya vandanam is performed in the morning as the first prayer after one bathes. In the old days people went to the rivers or the large temple water tanks for their bath. After their bath and before leaving the river (or any body of water) devotees will perform sandhya vandanam. The Vedas give these instructions on how to perform sandhya vandanam:
Standing knee deep in water while facing the rising sun, water is collected with both palms together. Then the while chanting the Gayatri mantra the water is slowly poured back into the river. This is repeated three times.
