Nathpanthis were a group of religious individuals who originated in the mediaeval era and assumed that the way to salvation lay in the realization of the formless one and via meditation of the same.
Nathpanthis believed that the path to salvation lies in meditation.
Therefore, they advocated intense training of the mind and body through practices like Yogasanas, breathing exercises and meditation.
The Nathpanthis, Siddhas and Yogis became popular among “low” castes and their criticism of conventional religion created the ground for devotional religion to become a popular force in Northern India.
