This is a very common issue for people. Most workplaces aren’t especially conducive to overtly spiritual attitudes or practices. First, one thing I wouldn’t do: proselytize or in any way to try to force other people to share your interest. Of course, if for some reason it comes up in a personal interaction and you feel it is safe and appropriate to discuss it with someone, that’s fine. But don’t beat people over the head with it—or worse, try to make them feel badly for not having the same interest. That would be not only inconsiderate but also a sure-fire way to piss people off—and virtually guarantee they go in the other direction. I know I would.
On a positive note, there are two types of things you can do. First, you can do things privately and inwardly that enforce your beliefs and practices. You can do quietly do japa (the repetition of a spiritual meaningful phrase) and you can use your breaks to do whatever practices you do. If you don’t have a private office, see if you can find some other space where you won’t be interrupted. Consider leaving the building, especially if it is a nice day or there is a nice park or plaza nearby. If it is allowed and you feel comfortable doing so, you can always put some kind of visual reminder in your work area. Perhaps the most important thing you can do is to actually employ your principles by being kind, considerate, supportive, and harmonious with your co-workers and boss. Try to practice what you are not preaching. You, all by yourself, have the ability to improve your workplace. Smile, be kind, help people, be of service, and relate to people from the perspective of what you see as their highest potential, even if they aren’t yet living up to it. Without ever saying a single “spiritual” word, you can improve your environment by helping others to be the highest versions of themselves.
