Thangka, a type of scroll painting featuring Buddhist religious themes, is created with mineral and organic pigments. The rules for Thangka painting have been handed down from the 7th century but modernization and greed are threatening this unique art form. Sitting on the floor of his monastic chamber, Kangtang Targyea scrutinized a cotton canvas painting of a white Tara.

The painting, which had taken him two months to finish, featured a seven-eyed goddess on a lotus and moon cushion. Her dark blue hair was adorned with diverse precious ornaments, with a luminous moon halo at her back.

Kangtang Targyea lives in a monastery in Wutun Village, a place dubbed as the "hometown of Tibetan artists" in Tongren County, a typical Tibetan area in northwest China's Qinghai Province.

Thangka, a type of scroll painting featuring Buddhist religious themes, is painted with mineral and organic pigments derived from such materials as coral, agate, sapphire, pearl and gold. The more pigments used, the more expensive the painting, explained Kangtang Targyea.

The rules for Thangka painting have been handed down from the 7th century, said the 46-year-old monk. The head and body must be perfectly proportioned, and the gold paint goes on after the pencil outline.

The right hand of the white Tara must have a gesture of an invitation to liberation, with the thumb and ring finger of her left hand holding a branch of utpala. The tip of the branch must be pointed at her heart - no higher, no lower.

Tongren is called Rekong in Tibetan, and it is famed for Rekong Buddhist arts like Thangkas, stone carvings and clay sculptures of Buddhist figures.

It is also famous for the notable artists who grew up there, in particular Shawu Cenam, Targyea's father, a famous Thangka painter in the 1930s.

In Shawu Cenam's day, Thangkas were used as religious objects in monasteries, not things for sale. Only monks had the painting skills.

Things are different now in Rekong, where "everyone - monk and layman - learns the skill and every family owns an atelier, as Thangka paintings are lucrative," said Kangtang Targyea.

In the past three decades, Thangkas have gained popularity among individual collectors from Chinese cities and foreign countries, and the price has been driven up, said Zhao Chunsheng, a member of China's Association of Collectors and the author of "Treasures of Thangka."

The price of Thangkas in modern times has ranged from 5,000 yuan (US$733) to several hundred thousand yuan, depending on the size, pigments, quality and the painter's popularity, Zhao said.

Pointing at a canvas depicting the Eighteen Disciples of the Buddha, Targyea said that he would sell the painting for at least 9,000 yuan, though the pigments cost only about 3,000 yuan.

"We now see more young men learning the art because it can bring more money," he said. About 1,000 people are able to paint Thangkas in Wutun, a village with a population of 1,700.

"On one hand, the market helps protect the art, in terms of attracting more people to learn how to paint and increasing the popularity of Thangkas," said Zhao.

"On the other hand, it might be harmful to the fine art."

Although thousands of Thangkas are produced in Rekong every year, only a few are good, Zhao said.Xihdao, a famed Thangka painter in Rekong, agreed. "Some young painters desire computers and fancy cars. It's irresistible to think of these desires when they are drawing. But back in our day, we only focused on the canvas, which is crucial for painting a good Thangka.

"In the past, we listened to Buddhist music when we were drawing, but now, youngsters listen to pop music while painting. How can they create good Thangka paintings while their hearts are elsewhere?" Xihdao asked.

"Most people who order Thangkas are businessmen from big cities like Beijing, Shanghai and Guangzhou," said Xihdao.
