Explanation:

The Nirankaris Movement was founded by Baba Dayal Das and it was a movement of purification and return. He called for the return of Sikhism to its origin, sometimes during 1840s and emphasised the worship of God as Nirankar (Formless). He rejected all kinds of idols, the rituals associated with idolatry and also the Brahmin Priests, who conducted these rituals. He also rejected those Sikhs, who were allied with the Brahmin Priests. They advocated the path to God was through worship based on meditation rather than complex ritual.
The Nirankaris also stressed the importance and authority of Guru Nanak and of Adi Granth. They focused on Guru Nanak, on Sikhism before the establishment of the Khalsa by Guru Gobind Singh at Anandpur and also before the militarisation of the faith. They stressed proper religious practice issued Hukamnamas to define its concepts of what was correct and also built a series of worship centres staffed by their own priests.
The Nirankaris were asked not to treat the women as unclean at child birth, take dowry at marriages, place neither lighted lamps nor blessed sweets, prasad, placed in rivers and also not to feed Brahmins as payment for conducting rituals.
