Toeghin Peulh, a village 30 kilometers south of Burkina Faso's capital Ouagadougou that has become a magnet for the sick and the desperate.
Among the rivers of humanity are men whose feet have been chained, people who have been crippled, others who are said to be possessed, cursed by bad luck or haunted by spirits.
They are the desperate of a nation buffeted by poverty and ravaged by a bloody jihadist insurgency, with only the thinnest social safety net.
"We tried every kind of treatment, but none of them worked," said Awa Tiendrebeogo, a relative of a man suffering from chronic dizziness.
"Then someone we know told us of Adja, and we came here."
Adja is the nickname for Amsetou Nikiema, a young woman who says that she was haunted by visions during her childhood in rural Burkina - and suffered cruelly at the hands of her family as a result.
Three years ago, word spread that she had carried out a miraculous healing. From there, her reputation snowballed.
Today, drawing on traditional medicine and what she says is a spiritual guide, she practices in an open compound built in the bush with the help of wealthy donors -- she does not charge, but donations and other offerings are discreetly encouraged.
Officially, just nine percent of Burkina Faso's population say they are animist.
But this figure is widely considered to be an underestimate. Traditional beliefs run deep, often co-existing among the country's Muslim majority and Christians, and the authorities are tolerant of claimed healers.
"The saying here is that people criticize the tradition by day and practice it by night," said one of Adja's assistants.
Among those seeking her help are people said to have been victims of evil spirits, such as Fatoumata, a young woman who suddenly lost the use of her legs.
She lay motionless on the ground as Adja splashed her with holy water and slowly walked on her body, barefoot.
The prayers of the crowd rose a notch, mixing with the cries of other "possessed" people who were waiting their turn.
In Fatoumata's case, Adja failed. The patient did not get up, but the following case, also a woman, recovered the use of her legs.
- 'Suffer' -
Adja's believers say that her honesty in admitting failure to cure conditions that are beyond her powers is what attracts them to her.
"Adja's fame comes from her integrity," said Awa Tiendrebeogo, who said she had healed a relative from dizzy spells.
Adja told AFP her powers came from a "spiritual" entity that commanded her life and forbade her to lie.
Her sensitivity to the spirit world, she added, meant that at night those who were jealous of her would cast spells on her. She pointed to what she said were painful, invisible wounds on her arms and legs and body.
She was surrounded by a host of bodyguards, assistants and biographers, but seemed cheerful and spontaneous.
"The reason why I laugh all the time is to ease people's plight," she said. "People used to hate me when I was a child, and so I wanted people to like me."
"Because of my family, because of the way I was mistreated by them, I became the person I am today, and I know how to take care of someone," she said.
"And if you don't suffer during your childhood, you will never succeed in life."
