Vivekananda gave us this idea that they are all developments of that one stream of thought. It's not that one is right or the other is wrong. They're all right. From different perspectives, each of them is true. Sisthanivarita goes on to say another, the greatest teaching, the master key which will unlock all of Vivekananda's teachings. She says: The many and the one are the same reality. Seen by different seekers in different minds, in mind sets,. in different times, in different attitudes. That is God. And philosophy, theology, from the very beginning till now, has at this struggle.
On the auspicious occasion of Swami Vivekananda's Tithi Puja, Swami Sarvapriyananda speaks on his powerful and timeless teachings.
