I'm a perfect housemate—when I live alone. When I share my living space with a relative, a friend, or a lover I discover me.
I know when you replace a roll of toilet paper you place it so it hangs down the front not the back. I know you leave butter in a covered dish on the table so when I spread my toast I don't tear it.
We only discover our ability to be true practitioners of the Buddha Dharma when we live in community with other people, other living beings.
