According to Swami Dayananda Saraswati, the Upanishads hold great significance as they are the source of knowledge about the ultimate reality, or Brahman, and the means to attain it. He believed that the Upanishads are not just a collection of philosophical texts, but they are a guide to living a meaningful and purposeful life.

One of the main teachings of Swami Dayananda Saraswati is that the Upanishads emphasize the importance of self-knowledge. He believed that true knowledge is not gained through external sources, but through introspection and understanding the true nature of the self. The Upanishads, therefore, serve as a guide to help individuals discover their true selves and attain liberation from the cycle of birth and death.

Swami Dayananda Saraswati also emphasized the practical aspect of the Upanishads. He believed that the knowledge gained from the Upanishads should be applied in everyday life to achieve inner peace and harmony. He taught that the Upanishads provide a path for individuals to live a life of righteousness, compassion, and selflessness.

Furthermore, Swami Dayananda Saraswati stressed the importance of the Upanishads in understanding the true nature of the world and our relationship with it. He believed that the Upanishads teach us that everything in this world is interconnected and that we are a part of a larger whole. This understanding can help individuals develop a sense of unity and harmony with the world around them.

Another significant aspect of the Upanishads according to Swami Dayananda Saraswati is their emphasis on the concept of karma. He believed that the Upanishads teach us that our actions have consequences and that we are responsible for our own destiny. This understanding can help individuals become more mindful of their actions and make conscious choices that align with their ultimate goal of self-realization.

In conclusion, Swami Dayananda Saraswati saw the Upanishads as a guide to understanding the true nature of the self, the world, and our relationship with it. He believed that the teachings of the Upanishads are not limited to a particular religion or culture but are universal in nature and can benefit anyone seeking self-knowledge and spiritual growth.
