That's just a sample of the restrictions McDaniel imposes in an effort to help students become more observant, aware and disciplined. Each constraint represents an actual taboo observed by a monastic religious order.

"I've found in the past that students take this extremely seriously," said McDaniel, who has taught the class twice before. "I've had very few people who try to get away with things, and you can always tell when they are."

The discipline starts with a dress code for class: White shirts for the men, black shirts for women, and they must sit on opposite sides of the class. No makeup, jewelry or hair products. Laptops are prohibited; notes can be taken only with paper and pen. And don't even think of checking your cellphone for texts or email.

The course, which focuses primarily on Catholic and Buddhist monastic traditions, stems in part from McDaniel's own history. An expert on Asian religions, he spent a portion of his post-undergraduate life nearly 20 years ago as a Buddhist monk in Thailand and Laos and says he's both a practicing Buddhist and a practicing Catholic.

Restrictions outside class are introduced gradually: Students sacrifice caffeine and alcohol during one week, then swear off vegetables that grow underground in another. The latter rule stems from an extremely non-violent sect that eschews such produce because uprooting the food could kill insects, McDaniel said.

The real test is a full month of restrictions that begins in mid-March. Students can only eat food in its natural form; nothing processed. They can't eat when it's dark, nor speak to anyone while they eat. They must be celibate, foregoing even hugs, handshakes and extended eye contact. No technology except for electric light. They can read for other classes, but news from the outside world is forbidden.

So why would anyone sign up? It could be because McDaniel requires no term papers or exams. But sophomore Madelyn Keyser, 20, of Castro Valley, Calif., said that's misleading.

"In reality, it's much harder because your grade is based entirely on your participation and your integrity," said Keyser.

As a nursing major at the Ivy League school in Philadelphia, Keyser said she hopes the class will help her become more observant and a better listener to her patients.

Students also have to write in a journal every 30 minutes during their waking hours. And required course research cannot be done online — students must consult books and librarians, or have conversations with religious leaders.

Freshman Rachel Eisenberg said she enrolled because it's important "to figure out yourself before you can really help other people."

"It would give me a chance to really listen to myself and focus on my needs and feelings," said Eisenberg, 18, of Miami.
 

Keyser and Eisenberg are among 17 students in the class, a group carefully chosen from among nearly 100 applicants. McDaniel said he winnowed the list by contacting each student to make sure they understood what they were in for.

The numbers thinned quickly. One cited an inability to be without Facebook, McDaniel said, while another said she couldn't go a day without talking to her mother on the phone.

There are some exceptions to the rules, such as if another class requires students to watch a film. But any other infractions require confessions and acknowledgement in their journals.

In one recent class, three students were disciplined for the minor slip of having the labels of their T-shirts exposed, violating the dress code designed to enforce conformity. As a punishment, McDaniel made them compile a list of the countries where every one of their shirts was made.

McDaniel stresses he's not advocating for a total lifestyle change. He uses technology as much as the next person and is now married with children.

But if someone is forced to just listen for a month, he is more aware of how he speaks, McDaniel said. If someone can't talk while she's eating and has to count each chew, she'll think more about her food, he said.

"'It's not about individual restrictions," said McDaniel. "It's about building hyperawareness of yourself and others.'"
