In this course we make a detailed study of three of the shortest of the major Upanishads: the Kena, the Ishavasya and the Mandukya. Despite the brevity of these works, they must be regarded as fundamental to the doctrines taught by Hindu Dharma. In many ways they can be regarded as foundational works for Hindu religious teachings. Because these Upanishads are so short we can undertake a detailed verse-by-verse study, with reference to the commentary of Shankaracharya and others. As we proceed we will reflect on the significance of the teachings in relation to the contemporary practice of various forms of Hindu spirituality.
