Answer: Only by its purpose, what is it exactly that you want. That is the only difference.
I can enjoy life, travel, sit with friends at a good table, and so on. And whether these actions are corporeal or spiritual depends on how we fill them, with what intention, what we talk about during the meal and in other situations.
Everything is conditioned by what goal everyone pursues being together with their friends. If our goal is to unite, to show each other how we want to be internally connected, then this is a spiritual action.
Everything depends only on our intention, on how much we strengthen our connection so that the Creator begins to manifest between us.
