This Mantra is one of the most beautiful Mantras to me. When I'm down, or something bad is happening, I keep repeating this Mantra and it always helps me. It's from the Brhadaranyaka Upanishad, and is about 2500 years old. These are the Words: Om Asato Ma Sad Gamaya Tamaso Ma Jyotir Gamaya Mrityor Ma Amritam Gamaya Om Shanti Shanti Shanti The Meaning is: Lead me Through the Illusion to the Real Through the Darkness to the Light Lead me through Death to Immortality Om Peace.
