Imagination plays a most significant role in the spiritual life. Suppose you are not having good meditations, but six months ago you had a very good, powerful, high meditation. What you can do is try to imagine that powerful meditation. Then your imagination will become reality. After fifteen minutes or half an hour, you will get a good meditation. Vivekananda was such a great spiritual figure, yet sometimes for six months at a time he did not have a good meditation. What did he do? He used to imagine a time when he did have a good meditation, and inside his imagination was aspiration. So imagination is very good.
