The thought-form whose reverence helps him to keep concentrated, the mental image whose worship holds his attention quite absorbed, justifies a place for itself in the meditator's method. Only at an advanced hour may he rightly put them aside. But when that hour arrives, he should not hesitate to do so. The devotional type of meditation, if unaccompanied by higher metaphysical reflection, will not yield results of a lasting character although it will yield emotional gratification of an intense character. Overself is only an object of meditation so long as he knows it only as something apart from himself. That is good but not good enough. For he is worshipping a graven image, not the sublime reality. He has to rise still higher and reach it, not as a separate "other," but as his very self.
