Sri Aurobindo translates Mundaka Upanishad, Chapter 3, Section 1, Verse 6: “It is Truth that conquers and not falsehood; by Truth was stretched out the path of the journey of the gods, by which the sages winning their desire ascend there where Truth has its Supreme abode.”
The Vedic Rishis referred to the Divine manifestation as “the Truth, the Right, the Vast”. The Upanishad’s references here to “Truth” must be understood in the context of the Vedic conception. They are not referring here to the limited truth of speaking factual statements in the external world, but to the larger concept of the universal creation as an expression of the Truth of the Divine. The normal human standpoint is illusory, a falsehood, and therefore misleading as to the implications of how we understand the significance of life, and of the individual.
We see the sun rise in the morning and set in the evening, transiting across the sky. It is however falsehood to believe that the sun is thereby rotating around the earth. The limitations of the falsehood kept humanity imprisoned in a limited viewpoint which still is active today in the way we understand the planet, and the relationship of all the people living on the planet. We do not yet fully comprehend the reality of oneness of all beings in the world, and the larger significance of this world within the solar system, the galaxy and the universe. We still live under the influence of falsehood in this sense, as in many other areas of our lives. We believe we can destroy species, change the chemical balance of the atmosphere, and not have consequences because we believe in the individual ego and its gratification as a central theme, rather than recognizing the truth of interdependence.
The fruit of living in the falsehood is suffering. When we shift our view to the actual reality, to Truth, we find we can address the issues of life in a new way which is based in harmony and oneness. This leads to true solutions and is the path for the sages to shift to the Divine standpoint as the basis for their lives.
