Most Gurus and disciples have changed names. Actually, there is no ritual or religious importance to changed names. But, it helps psychologically: when you think an ordinary name, suppose your friend name, you think all about his history, his past, his behavior, attitudes and so on, and when you think about the name such as "Buddha," "Shiva," "Ganga," etc, you start having some enlightening image in your mind.

Changed name helps to a person and others, who call him. The basic idea is, the name should not touch the "past," and with a new name, the new life should start, as fresh and enliven as the new name is.

In India, you can find most of the Gurus and their disciples with changed names. Often, in Satsang, a Guru, lovingly, gives a new name to his disciple. If you want to change your name, you can ask to your Guru, or can change name yourself.
