Johnson, who has been working at Seven Stars for over 10 years, has fond memories of the place.
He moved with it when it left its original location at 58 JFK St., where it was called Shambala, over a decade ago.
A phone call interrupts the quiet ambience of the store.
The woman on the line is inquiring about whether the book she ordered--How to Know the Higher World--has come in.
"All kinds of people shop here," Johnson says with a smile after assuring her that the book had arrived.
He lists some recent hot sellers, proof of the customers' diversity: Horns and Crescent, a Cambridge-based pagan magazine; Tibetan jewelry and books; and Conversations With God, Neale Donald Walsch's New York Times bestseller.
While customers are drawn to the bookstore's atmosphere, Seven Stars does a large part of its business is done in special orders from around the world.
"We had one of our customers who got a degree from Oxford tell us that there are only three esoteric, occult top-level bookstores in the world, and we are one of them," Johnson says proudly.
Also, each year a Sorbonne professor from Paris comes to Boston and orders books from the store.
"He'll order boxes of books, ask me to ring them up and ship them to him in France," Johnson says, smiling. "He can't get them any-where over there."
But for such a diverse clientele, Seven Stars has a multitude of more mainstream books.
If you're not in the mood for High Times, the magazine for marijuana smokers (this week featuring the Beastie Boys' DJ Mixmaster Mike), then you can also find books on Bill Clinton, environmentalism and exercise.
Seven Stars is located at 731 Mass. Ave. in Central Square.
