The more you enter into meditation, the more and more imagination will try to distract you. It is not a new phenomenon, it has always happened. All the great meditators have come across it. Buddha is distracted by Mara, the god of devils. Jesus is distracted by the devil. Sufi mystics are distracted by Satan. There is no Satan, no Mara, no devil — the real devil is in your mind, the imagination.
