During Vishwaguruji's Satsang (Melbourne 22.2.2020) he talked about the concept of oneness and universality by giving a few examples to demonstrate this.

He highlighted how most of us think we are simply an independent, singular entity but this is not so. We are in fact a united reflection of many souls making up the one universe. He described how every drop of blood within you seems so tiny but even within it there are many micro cells coming together to make up that one drop. There is life within each cell. And each of those cells come together to create a drop of blood, and many drops of blood come together within you and so on.. 

The point here is that there is life within life – your blood is alive within you. Each and every organ within you is the same. This is inner yoga; becoming aware of the pulsating oneness within us. And it continues. The oneness does not stop there; we continue to make up the chain as entities linked to one another bringing the universe to life. We are life within life making up a bigger scenario.  So do not think that you are alone, or disconnected. You are part of the Universe.
