Sri Aurobindo

What exactly is meant by meditation in Yoga? And what should be its objects? The difficulty our correspondent finds is in an apparent conflict of authorities, as sometimes meditation is recommended in the form of a concentrated succession of thoughts on a single subject, sometimes in the exclusive concentration of the mind on a single image, word or idea, a fixed contemplation rather than meditation. The choice between these two methods and others, for there are others, depends on the object we have in view in Yoga.
