How new these ideas were at that time! The first great idea was that the guru must be a knower of Brahman. This is the most important qualification, for only the knower of Brahman has the power to transmit spirituality. The transmission of spirituality from guru to disciple was a startling and fascinating idea to the Protestant type of mind in the West. Spirituality can be transmitted! This, then, explains the doctrine of Apostolic Succession. This is why the Church of Rome still believes that the spiritual power of Peter has been transmitted from Pope to Pope. Be that as it may, today in India it is believed, nay, known with certainty, that the guru can transmit his spirituality to a disciple.
