The video above presents the idea of the self, who you really are at a fundamental level, being one with the cosmos (everything there is), as well our self being identified with humanity itself.
There is also the fundamental idea, which differs from our experience in everyday life, that we are something which has come from Planet Earth. Many of us, from the standpoint of our beliefs, see ourselves as being something foreign from nature. However, when we really look at ourselves, we see that we not something foreign, but something which has come from the Earth. And thus, we are connected with all of life.
When we regain our recognition of relationship with Planet Earth and the life born from this place, our perspective is shifted in a way where we might live in better harmony with the world. We may find deeper peace within ourselves, as connected with all of life.
