Śailādi said: I shall mention the necessary qualifications as revealed by preceptors and the scriptural texts. The nomenclature of Śaiva preceptor (the propounder of Śaiva doctrines) is based on. his gravity and not otherwise. Ācārya[2] (preceptor) is so called because he practises the doctrines himself, stabilises others in the practice of those doctrines and gathers together the topics mentioned in the scriptural texts.
