According to Swami Sivananda the Linga represents the Nirguna Brahman , formless and without attributes, ol Supreme formless, Shri Shiva , which is the essence indivisible, pervasive, eternal, auspicious, ever pure, immortal of the vast universe, the soul immortal sitting in the chamber of the heart, and the inner Self or Atman which is identical to the Supreme Brahman.
He also argues that even if the Agamas do not derive their authority from the Vedas , they are not mutually antagonistic. Some scholars believe that anything that contradicts the Vedas or is inconsistent with its spirit is not authoritative. According to this perspective, the conceptualizations Puranic and tantric are secondary to the Vedas and Agamas which are Vedic in spirit. From this point of view, the conceptualization of the lingam as a phallic symbol does not have much relevance as Veda and Agama not support this interpretation.
