Hindu texts "Śruti" refers to the body of most authoritative, ancient religious texts, believed to be eternal knowledge authored neither by human nor divine agent but transmitted by sages ("rishis"). These comprise the central canon of Hinduism. It includes the four Vedas including its four types of embedded texts - the Samhitas, the Brahmanas, the Aranyakas and the early Upanishads. Of the "Shrutis" (Vedic corpus), the Upanishads alone are widely influential among Hindus, considered scriptures par excellence of Hinduism, and their central ideas have continued to influence its thoughts and traditions. The "Smriti" texts are a specific body of Hindu texts attributed
Vedas inspired later Hindu scholars such as Adi Shankara to classify each Veda into "karma-kanda" (कर्म खण्ड, action/ritual-related sections) and "jnana-kanda" (ज्ञान खण्ड, knowledge/spirituality-related sections). The texts considered "Vedic" in the sense of "corollaries of the Vedas" is less clearly defined, and may include numerous post-Vedic texts such as the later Upanishads and the Sutra literature. Texts not considered to be "shruti" are known as "smriti" (Sanskrit: ""; "the remembered"), or texts of remembered traditions. This indigenous system of categorization was adopted by Max Müller and, while it is subject to some debate, it is still widely used. As Axel Michaels
