The single-syllable song is quiet, almost an ambient hum. But Eckists believe it's a powerful love song to God.
The singing of Hu — pronounced "hue" — is a central practice of Eckankar, a New Age religious movement that claims tens of thousands of adherents in 100 countries and recently marked its 50th anniversary.
For more than three decades, the unlikely international center for the little-known faith has been Chanhassen.
The religion's tenets — soul travel, reincarnation and the significance of dreams — might seem odd or otherworldly. But the campus has quietly become part of Chanhassen's fabric: hosting Hu singing events, opening its walking trails to local residents, welcoming followers during its international conferences twice a year.
Things weren't always so serene. When Eckankar's leaders were buying land and planning to build their temple in the 1980s, some Chanhassen residents balked at the new neighbor.
"There's always some trepidation whenever you have a religion outside of the traditional Christian religions we have in Minnesota," said Todd Gerhardt, Chanhassen's city manager. "People were scared of the unknown."
With 173 acres, Eckankar is the fourth-largest landowner in Chanhassen, behind the Minnesota Arboretum, the late musician Prince and Bluff Creek Golf Course, Gerhardt said.
Now, he added, "We have no issues with Eckankar at all. People have accepted it, and everyone kind of goes about their day-to-day life out here."
