What is the inner significance of the rosary? At the time of meditation, the worldly man is harassed by worldly thoughts. The rosary teaches that until unimpeded meditation becomes possible, the aspirant should persevere, leaving behind thought after thought. The beads represent thoughts and they are pushed back. The thread passing through the beads represents "the all-pervading ideal." With patience and perseverance, thoughts are subdued and, as a result of unimpeded meditation, the ideal is realized. The head bead which is bigger than the rest represents the point of realization, that is, God, in whom the universe has its birth and in whom it ends.
