We must know who we really are, knowing and knowing are 2 different things. We know the name Satoshi for example, but we don't necessarily know him, whether he is an individual or an organization.
Knowing ourselves more deeply can make us know what potential is in us, what our abilities are, what makes us superior to other people, we will know if we know ourselves deeply.
Indeed, this may be a little confusing for some people, because sometimes we think it is impossible for us not to know ourselves. The fact of the matter is that we don't necessarily know ourselves, because this is something that is comprehensive.
