The thought of separation from others isn’t truly separation, it’s only a thought, so when the thought does arise, if it isn’t attached to, there’s a connection to all of life.
Because of the Conditioned Mind when someone is from another part of the world and they’re different looking on the outside, they’re seen as being separate, but the only separation from anything is the story of separation. There is no true separation and when one understands that the nature of all separation is only from the way one is conditioned, it ceases to exist. At the core of this understanding is a oneness within and thus a oneness with everything. This includes insects, animals, fish, plants, and humans, in essence the entire Universe, but don’t miss interpret this, it’s not a concept or theory. It can only be truly sensed when the mind is very still and only in the context of one’s mind being absent of any thought about it.
There has to be a oneness within oneself before there can be oneness with anyone else. If this doesn’t occur it’s because one is consumed by the thought realm and the thought realm is controlled by the Conditioned Mind. Please don’t take this lightly, it’s the reason, greed, hate, and delusion are the default setting of so many minds. If there isn’t quietness, there’s noise and if there’s noise it’s derived from one’s conditioning. Sit with this and notice when separation arises and what’s at its core. Let it pass without labeling it, just watch it’s core and don’t attach to it. Remember the thought of separation isn’t true separation, it’s only a thought and when it arises as it will, if the thought isn’t attached to, it will be impossible to be separated from anything.
