The appearances of the Sadhus vary from brightly coloured face paints and decorations, to minimalistic practical clothing, but they all represent the fundamental values and meanings of Hinduism.
Danish photographer Jan Møller Hansen visited the ancient capital city of Kathmandu between 2013 and 2016 and documented the mysterious holy wanderers.
He said: “The Sadhus are travelling through cities, villages and forests, sleeping in temples, under trees by riverbanks or wherever they can find a suitable place to rest.
They wander between different holy places, which typically are sites with Hindu temples or confluences of rivers that are regarded as powerful sites.
"During the famous celebrations of the Shiva Rati festival at the Pashupathinath temple in Kathmandu, the Nepalese government, for example, will pay the Sadhus a daily allowance and provide them with food, drinks and ensure that their visit and stay wil be enjoyable.
"They have a lot of cultural meaning to many people.”
Despite the respect they receive from locals, being a Sadhu is a challenging life choice and requires a large amount of dedication.
The photographer said: "The Sadhus have left the material and ordinary life behind in favour of an alternative community devoted to God. I find that fascinating. But don’t be mistaken - it is a tough life.
"You live from day to day, are vulnerable and depend a lot on others’ kindness. As a Sadhu, you might not always be treated well either. I guess it requires a lot of strength and courage to become and live like a Sadhu."
