Names are powerful because of what they represent.
The more powerful the represented is,
the more powerful the name is.
The more you know what a name represents,
the more powerful that name is to you,
the more powerful that name is.
The most powerful name is that of the fully enlightened,
with perfect compassion and wisdom,
who vowed to bless all who are mindful of his name.
So powerful is his name,
that it can lead to Pure Land,
which can lead to Buddhahood.
