One thing: You must be attentive that our routine work–such as rising early, cleansing, chanting, temple worship, reading, sankirtana, etc.–should always maintained at the highest level of Krishna Conscious standard, as the smallest neglect or inattention to these matters of routine practices will cause all our other programs to fail. These things are the backbone of spiritual life. So it is natural that in these things like chanting regularly 16 rounds and holding daily arati and kirtana are observed faithfully, then people will be attracted and our preaching will have effect and the management of temple affairs will become very easy matter.
