An instructor testifying in a lawsuit filed over the Encinitas school district's yoga program demonstrated some basic poses inside a San Diego courtroom Wednesday.

At issue: are yoga poses religious in nature and can schools offer yoga instruction as part of its physical education program without promoting the religion or spirituality behind the practice?

Judge John S. Meyer heard testimony this week regarding Ashtanga yoga and a curriculum established within the Encinitas Union School District where students practice yoga as P.E.

The district established its yoga program with a $500,000 grant from the K.P. Jois Foundation. The hope was that yoga would help the elementary school students focus on studies, keep them calm and may even curb bullying.

All nine schools in the district are currently participating in the program.

However some parents objected when the program was launched in the fall of 2012. After complaining to the district, opponents sued claiming the classes are being used to indoctrinate children and "spread the gospel" of Ashtanga yoga. The plaintiffs want yoga classes suspended immediately.

Attorney Dean Broyles argues Ashtanga yoga is inherently religious and that teaching the poses is therefore a violation of the separation of church and state.

“There is no belief taught about any movement the child is engaged in,” the Encinitas school district's attorney Jack Sleeth said.

Encinitas Union School District Superintendent Timothy Baird Ed.D. testified Monday the instructors work for a third-party company paid for by the funds from the grant and are not district employees.

Baird also said he and his staff met with the yoga instructors before launching the program and removed images of yoga sanskrit and changed names of poses.

“Initially we made a conscious decision to remove some cultural context,” Baird said.

Yoga instructor Jennifer Nicole Brown said that after parents complained about the children chanting during yoga, they stopped including that in the lessons.

She described one pose as “criss-cross applesauce” which is used by teachers in classrooms all over the country. She even exited the witness box, took of her shoes and demonstrated the poses for the court. Watch: Instructor Demonstrates Poses Used in Class

“What we do in the school district is completely different to the way that I would teach adults in a traditional Ashtanga school,” Jennifer Nicole Brown testified.

The plaintiffs called expert witness Candy Brown, Ph.D., of Indiana University, to testify about the basic principles of yoga.

“Many yoga traditions, not just in the past but also today, share a religious goal and that goal is human salvation,” she said Tuesday. The associate professor said the goal could also include reincarnation or spending eternity with the Divine.

Professor Brown testified there were explicit references to Ashtanga yoga in the school’s curriculum including the same opening, same poses and the same closing.

“That frames this as something more than exercise,” Prof. Brown concluded.

The practice of asking students to reach up to the sun in the mountain pose was religious she testified.

The suggestion that posing one’s body equals a religious practice could be extended to closing of hands or bowing of heads “Yoga for Encinitas Students” attorney David Peck said.

“[Students] can dream about anything they want, they can think about pizza while they’re doing a pose,” said Peck whose son is enrolled in the yoga program.

The defense maintains the grant was for a health and wellness program and the children focus on breathing and the alignment of their bodies.

The plaintiffs contend that they aren’t arguing whether yoga has health benefits. They are arguing that a class of Ashtanga yoga be suspended immediately.

Note: The original version of this article included a point made under cross-examination where a defense attorney claimed Prof. Brown received grant funding from The Templeton Foundation which supports “organizations focusing on Judeo-Christian faith based ministries and institutions involved in furthering God's Kingdom.” Prof. Brown told NBC 7 San Diego, "I was funded by the John Templeton Foundation, which is NOT a Christian organization." We regret the error.
