Whenever I have free time I am chanting gayathri mantra. Gayathri mantra is given by Viswamithra Maharishi. Chanting of this mantra will effect on nerves and spiritual chakras. Gayathri mantra opens gates to the spiritual world. Some experiments proved that this mantra will effect on nerves and awakens spiritual centers. There are many people who are benefited from the chanting of this mantra. I am giving this mantra below.
AUM BHOOR BHUWAH SWAHA,
TAT SAVITUR VARENYAM
BHARGO DEVASAYA DHEEMAHI
DHIYO YO NAHA PRACHODAYAT.
After chanting of this for several times I feel vibrations in my body. Doing meditation after chanting will give more peacefulness.
