According to the science of Spirituality, chanting the Name of God is the recommended foundation of spiritual practice in the current era i.e. the era of strife. As compared to mantras, chanting can be done anywhere and at any time and is the most convenient spiritual practice. Chanting is the only practice which can be done continuously throughout the day.
Any repeated thought or action forms an impression, which if reinforced becomes a center. This is similar to how a footpath is created in a field. Only if one were to walk in a grassy field repeatedly would a footpath be created. This is the same principle used to create the Chanting devotion center. In the process, the other impressions and centers get ignored and reduced until they cease to exist. So this is another effective way in which the devotion center cleanses the subconscious mind.
