namaparadha | नामापराध
An offence against God is called namaparadha (Devanagari: नामापराध ISO15919: nāmāparādha). Offence against His names, forms, attributes, lilas, abodes or His Saints robs one from all fruits of devotional practice.
Above all offences is the offence against His Saints. They are dearer to Him than His own self.
All these are unforgivable and one has to bear the ill fruits of these offences.
