There are other ways to God-realization, among them the practice of tevunah, contemplative comprehension of God's infinite and all-encompassing nature.
I teach tevunah using two Hebrew texts. The first is from the daily Jewish liturgy, Esa einai el heharim, me'ayin yavo ezri, "I lift up my eyes to the mountains, from whence (me'ayin) will my help come?" The mystical meaning of the prayer comes from the play on the words Ayn and ayin. Read mystically as me'ayn rather than me'ayin the text says, "I lift up my eyes to the mountains from the Divine No-thing (God) my help comes."
The second text is Shiviti Adonai l'negdi tamid (Psalm 16:8). While the literal meaning of the Hebrew is "I place God before me always," the mystical understanding is "I see God equally before me always." That is, whatever I see is a manifestation of God.
The practice is this: Sit comfortably and lift your eyes gently so that they rest on the horizon. If you have hills or mountains to provide you with a focal point, rest your gaze on the point at which they meet the sky. If not, gently lift your eyes skyward so that you see nothing in particular and simply gaze at the vastness of sky. Begin by reciting or chanting Esa einai el heharim, me'ayin yavo ezri. Do this simply to settle the mind, and when you feel settled cease the repetition. Do not control your thoughts, nor even take excessive note of them. Whatever arises in your mind, let it go. Do not become angry with yourself if thoughts and feelings continue to arise, these are not under your control. Rather greet each one as another opportunity to surrender; that is, let it rise and fall of its own accord without your active participation at all. If your mind becomes agitated return to esa einai, but do not make it a rote repetition. Let it go when the mind is once again calm. In time a sense of growing spaciousness will arise in you. Your mind will become as wide as the sky, making room for whatever clouds arise without identifying with any of them.
Practice this for twenty to thirty minutes, and then shift your gaze to the world around you. See everything from the perspective of Ayn and mochin d'gadlut (spacious mind), and remind yourself, Shiviti Adonai l'negdi tamid — everything you see is a form of the formless, a manifestation of God. If you practice this several times each week you will find that you spend more and more of your day in this state of spacious awareness, engaging Yesh (form) with an openness arising from Ayn (emptiness), and knowing both to be aspects of God.
