A mantra is a sound or a vibration that becomes very powerful when you repeat it. Singing the ancient words with subtle intentions help you to reach a deep state of meditation. By simply repeating the mantras, you can disconnect from your thoughts. The mantra becomes more abstract so it can lead you into a place of pure consciousness. Each mantra with its different sound has another effect on the human psyche. The sound vibrations penetrate every cell of the body.
On this page you can sing along with me and my lovely Shruti box, an instrument that is similar to a harmonium and provides a sound to support the mantra.
