Yēta is the second of the Three Certainties of Life, which is Change/Journey. Life is always a journey. From A to B, or from birth to death, or poverty to riches, or simply the heartbeats between each breath. The process of the various types of journeys that are inevitable in life, also always brings change.
The symbol/hieroglyph for Yēta was originally a road set between two hills, which perfectly ebodies the most common understanding of a journey.
The symbol of Yēta without diacritics is pronounced “ya” (English “y” pronunciation).
