Swami Vivekananda's favorite mantra is that the sun does not illumine. The 14th mantra, which we did last time, was tare tare tai anit desham paramam sukham. Sukham means inconceivable ultimate joy or in one word that would be ananda.
Swami Sarvapriyananda teaches the Katha Upanishad, one of India's most revered texts which is also a part of the Vedas. It is a collection of philosophical poems representing a conversation between the sage Naciketas and Yama (god of death). They discuss the nature of Atman, Brahman and Moksha(liberation).
