("twice-born") is a word that means "twice-born." A brahmin (highest in rank), kshatriya (second in status to brahmins), or vaishya (third in status to brahmins) is a member of the three “twice-born” divisions in Indian civilization (third in status to brahmins).
Because these groups are ritually qualified to acquire the teenage religious initiation known as upanayana, which is sometimes referred to as the "second birth," they have been given this term.
Look up twice-born.
