Nice post :) important to shine some light on this subject since it’s really vastly misunderstood.
When a person whom believes and acts as a separate entity adds the concept of oneness to the beliefstructure there is often weird effects in behavior.
Like justifying touching another body without prior consent (this usually only happens in a spiritual context/gathering/festival since the person doing this intuitively knows he/she wouldn’t get away with it in on the bus to work). The spiritual community really needs to grow up in this sense, call out and react when behaviors like this is seen. It’s just simply wrong! Keep in mind that most people in the spiritual communities are people with deep wounds and it’s important that we help to look out for each other.

Oneness is a really really mature state of being, and it doesn’t have a sober place in a life until that maturity is there.
If oneness is a cool concept that one adds to ones beliefs it’s really not doing any good. Might feel good to trip out on the concept but it won’t give any long term benefits.

I would go so far as to say, forget about oneness. When it is truly seen for what it really is then one could start to learn how to live it.
It’s not about adding something to your life it’s an effect of loosing ones sense of individuality. It’s about loosing loosing loosing! It’s rarely a nice ride. Forget about it!

Love, respect, friendship/friendliness, compassion and contemplation (and don’t forget your self, treat your self with at least the same amount of love etc. as your fellow beings) will take you a lot “further” then the idea of oneness.
Peace
