Even down to ten times

"Even down to ten times" refers to people who say the Name as few as ten times. "Even down to" means that neither those who say the Name more than ten times nor those who only HEAR the Name are omitted or excluded from birth in the Pure Land." 

Shinran Shonin

The above passage is referring to the true entrusting (shinjin). On hearing Amida's Vow, "Save you as you are!" free of doubt (shinjin), the nembutsu of gratefulness and joy will flow, "Namo Amida Butsu, my Lord Buddha, thank you for saving me!" This is one utterance awakened from Shinjin.

When Shinjin has been settled, in ordinary days, every time when we come to think of Amida's Vow, it naturally calls to mind His Name of Great Compassion, and the nembutsu will naturally flow, "Namo Amida Butsu...." All these are the proof of Amida's realisation of our birth.
