Most of the time, people who speak in this way are imagining being spiritual to be something they can do on their own. I have come to think that genuine spirituality doesn’t work that way. In the first place you need a tradition through which you can receive deeper wisdom about how to live than what you can discover on your own. You also need teachers who can help you learn to inhabit that tradition, and you need a community that will encourage you, but also hold you accountable, as you attempt to live out the desired way of life. You can certainly reject particular communities as unhelpful or counterproductive, but you need to find one that can be your community.
