The Holy One, Blessed is He, has many names and one of these is "Yah" the Name-Sound He used to create the universe. "Yah" is the direct reverse of the Ches and Yud in the word Chai. The Midrash says that the power of the Divine Names keep the particles of the universe suspended in a life force (Chai). The kabbalah teaches Hashem's Name "Yah" as the reverse Chai, is hidden in all things even inanimate objects, whose essence is life in the upper worlds. Here, the Chai is hidden in the poppy bloom, where only the drop-shadow reveals its exact positioning.
