Gerson describes different religions (Judaism, Christianity, Buddhism) as being more focused on either good deeds or inner contemplation.

I think it would be more accurate to say that each religion has elements of both inner contemplation and outward good deeds.  The stereotypical American view of Buddhism may be one of "retreat," both as a philosophy and scheduled event.  But in truth there are many Buddhist and Buddhist-inspired organizations seeking to actively change the world in various ways, in this lifetime.
