We often explain the age-old practice of meditation on a verse, particularly the verse from the book of Psalms: Shi’vi’ti HaShem L’negdi Tamid. “I place the Eternal before me always” (Psalms 16:8). Some do this by sitting in front of a wall hanging, known as a Shi’vi’ti, a traditional wall card, poster, or plaque with the verse from Psalms on it. Some of these wall hangings are elaborate works of art, with beautiful illustrations and other scriptural verses surrounding Psalms 16:8. The Hebrew letters of God’s name (YHVH) are often arranged vertically; they become the focus for visual meditation. Various teachings throughout the ages describe this practice:

Many people write the name YHVH on a piece of parchment … and keep it in front of them while they pray, according to the way of "I have placed the Lord before me always." And this brings awe of God into their heart and clarified your soul to purity.
--Yitzhak Buxbaum in Jewish Spiritual Practices

They then strive to keep the image of God’s name before them throughout the day, without any external visual aids. Visualizing God’s name encourages one to be aware of God’s Presence – in every action, in every interaction.
