Definition - What does Niranjan mean?
Niranjan is a Sanskrit word that has multiple meanings and uses. It means “pure,” “spotless,” “simple,” “truthful,” “great” and “without bad attributes.” It is also a name for the Supreme Being. The word is derived from the Sanskrit root words, nir, meaning “no” or “without”; and anjan, meaning “impurity,” “fear” or “lack of knowledge.” Anjan also refers to the sense of self and possession, so niranjan can mean a non-attachment to possessions and self.
As it refers to the Supreme Being, Niranjan is an incarnation or another name for Krishna and for Shiva.

Niranjan is also used as a male name or base of a name in India and neighboring countries. The female version of the name is Niranjana. For example, Niranjanananda was a 19th century monk and disciple of Ramakrishna. Swami Niranjanananda Saraswati, also known as Swami Niranjan, is a modern-day yogi who succeeded Satyananda Saraswati, founder of Satyananda yoga and the Bihar School of Yoga.
In a religious context, Niranjan is used in mantras to refer to the Supreme Deity. Nath yogis (a branch of Shaivism) use the term Alakh Niranjan as a synonym for the Creator.
