SANAKADIKA (SANAKA etc.) SANAKA, SANANDANA, SANATANA and SANATKUMARA
SANAKADIKA (SANAKA etc.) SANAKA, SANANDANA, SANATANA and SANATKUMARA (Sanakadika pertains to all these four names) Sanaka and Sananda (Sanandana) could not know the limits of the Lord. (Asa Kabir, p. 478) Sanaka, Sanandana and Narada Muni serve Thee and always meditate on Thee, O Lord! (Gujri M. 4, p. 507) The sages of gods like Sanaka, Sananda, Shiva and Shesha Naga could not know Thy secret, O Lord! (Dhanasari Kabir, p. 691) Sanaka, Sanandana and many persons observing religious austerities ferried across the world-ocean by the grace of the Guru.
(Bhairo M. l, p. 1125) Sanakadika and Brahmadika (Brahma etc.) sing, also Suka and Prahlada sing the Praises of the Lord. (Sarag M. 5, p. 1224) Brahma etc., Sanaka etc., Sanaka, Sanandana, Sanatana and Sanatkumara, even for them, the Abode of the Lord is difficult to attain. (Asa M. 5, p. 401) In Bhagavata Purana, it is written that Brahma, while creating the world, after some initial failures, created four Munis (sages) viz., Sanaka, Sanandana, Sanatana and Sanatkumara.
But they did not like the work of creation and absorbed themselves in austerities and worship of the Lord-God. In this way, the very purpose of further creation by Brahma was defeated. This filled Brahma with great rage, from which sprang forth Rudra, who carried on the work of creation.
