By Swami Harshananda
Naigamas literally means ‘those who accept the authority of the Vedas’.
Some sections of the śaivas, followers of Śiva and Śaivism, who accept the authority of the Nigamas or the Vedas, like the Pāśupatas, are sometimes called ‘Naigamas’. ‘Naigama’ also means the Upaniṣads or Vedānta and a section of the Vedic dictionary called Nighantu.
