In the Vāyu Purāṇa an ācārya is defined as one who knows the import of all Vedic literatures, abides by their rules and regulations, and teaches his disciples to act in the same way

CC Adi 1.46, Purport: The spiritual master is also called acarya, or a transcendental professor of spiritual science. The Manu-samhita (2.140) explains the duties of an acarya, describing that a bona fide spiritual master accepts charge of disciples, teaches them the Vedic knowledge with all its intricacies, and gives them their second birth. The ceremony performed to initiate a disciple into the study of spiritual science is called upaniti, or the function that brings one nearer to the spiritual master. One who cannot be brought nearer to a spiritual master cannot have a sacred thread, and thus he is indicated to be a sudra. The sacred thread on the body of a brahmana, ksatriya or vaisya is a symbol of initiation by the spiritual master; it is worth nothing if worn merely to boast of high parentage. The duty of the spiritual master is to initiate a disciple with the sacred thread ceremony, and after this samskara, or purificatory process, the spiritual master actually begins to teach the disciple about the Vedas. A person born a sudra is not barred from such spiritual initiation, provided he is approved by the spiritual master, who is duly authorized to award a disciple the right to be a brahmana if he finds him perfectly qualified. In the Vayu Purana an acarya is defined as one who knows the import of all Vedic literatures, abides by their rules and regulations, and teaches his disciples to act in the same way.
