In the Upanishad God is described as “The Peaceful, the Good, the One”. His peace is the peace of truth which we clearly see in Nature. The earth moves and the stars, every cell is moving and working in this tree, every blade of grass in this field is busy, and every atom of this evening star is restless, but peace is in the heart of all this movement – this movement which is creative. The movement which lacks this inner peace destroys. God, as the Peaceful, is revealed to him who has attained truth in his life, the truth which is ever active and yet which has an immensity of repose born of the mastery of self. It is not the loss of energy, the waning of life, which is peace, but their perfection.
An ignorant man finding himself in a factory for the first time in his life, is frightened at the bewildering medley of movements, but he who knows it is struck with admiration at the concentration of purpose dwelling in its centre, unmoved. This takes away all misgivings, and the perfect correlation of activities appears as beautiful. This is the peace which belongs to truth.
