God's Essential Name Havayah is spelled in Hebrew: yud-kei-vav-kei. According to the Jewish law, we are forbidden to pronounce the Name Havayah as it is written. Therefore, throughout out web site when spelling out the Name Havayah we have replaced the Hebrew letter hei with kei, as accustomed. Even during prayer it must be pronounced: Adonay ("my Master"). Here though, when meditating (without pronouncing) one may and should meditate on its four letters in Hebrew as they are truly written:yud-hei-vav-hei
God's essential Name Havayah is the Eternal Being, the Divine power that continuously brings all of reality into being
The above meditation is available in written form in "Living in Divine Space," a 288 hard cover book on Kabbalah and Meditation by Rabbi Yitzchak Ginsburgh.
