The EBTs are our source of what the Buddha taught. Attaining some kind of inner peace will take place as one follows the Buddha’s teachings, but that isn’t the ultimate aim. As @sujato said in another discussion:
As for dealing with the real world, this quote from the Chinese parallel to AN 4.95 can guide us in many life situations::
There are four types of persons: one person aids himself without aiding others, one person aids others without aiding himself, one person neither aids himself nor aids others, and one person aids himself and also aids others.
The person who neither aids himself nor aids others is the most inferior person. [If] a person aids others without aiding himself, he is superior [to that]. If a person aids himself without aiding others, he is superior [to that]. If a person aids himself and also aids others, he is the highest; a person like this is supreme.
