“In search of enlightenment”
The Sadhus are a Hindu ascetic and follow the path of austerity and penance to achieve enlightenment in their way.
They dedicate their existence to meditation, renouncing all material bond and in this way to avoid the cycle of reincarnation and to accede to the desired Nirvana.
A Sadhu never stays in the same place for a long time. He is a traveler and in his way he has left everything.
