Samantabhadra means completely good 

 
It’s related to Emptiness, to the nature. So, the nature of the mind is unstained. It’s stainless from the beginning, so therefore it’s completely good. Samantabhadra means completely good. And why it’s good it’s. It is ideally unstained by either good or bad. Sometimes we think something is good, but why we think it’s good – because there’s a bad [thing]. So compared with that bad thing, this is good. It’s here due to your mind – how you think – it’s [good] or not good. We say Samantabhadra or completely good is unstained by either good or bad. 

 
If practice with this realization of Samantabhadra then it’s the best way, the quickest way to achieve enlightment, Hungkar Dorje Rinpoche
