A member of a Sikh reform movement founded in 1851 by Baba Dayāl Dās (1783–1855).
Dayāl Dās and his followers stressed the need for simplicity in worship and lifestyle, and rejected the use of idols. Although the Nirankaris are regarded as a sect by orthodox Sikhs, there is in fact now little to distinguish them apart from their veneration of Dayāl Dās and his successors as Gurus..
Origin
Mid 19th century. From Panjabi niraṅkārī from Sanskrit nir-ākāra formless + -ī.
