Both the parsha and the haftara describe the building of a sacred space, the former being the Mishkan (Sanctuary) in the desert and the latter being Solomon's temple in Jerusalem. These sacred spaces were created for the sake of G-d dwelling within us, as the Hebrew reads, "so that I may dwell within you," and not within the Sanctuary itself. We need houses, we need clothing to protect, we need synagogues and places of learning to raise our spirits and our minds higher, we need holy places to inspire us. G-d is not in these places; they exist solely for the sake of our realizing the spark of the divine within us, and then as aware of G-d's dwelling within, we will see G-d everywhere. "G-d was in this place and I didn't know!" -- Jacob was meaning in his heart, and then looked around at the whole world with a G-d perspective. The challenge we face at every moment is to know G-d within, and continually create a place in our awareness for that indwelling.
The Third Temple is the heart of a Jew. We cannot be commanded to know G-d; we are commanded to do things like blessings which set up the conditions. My knowing G-d within and without is dependent on my free will -- I have to want to. That is why all the trumah offerings for the building of the sanctuary were voluntary. Everything, then, becomes an opportunity to freely offer for the dwelling of G-d -- the sanctuary is always being built, each time I will it in my heart and offer my life for a higher purpose. Each time I give of myself, I receive G-d. Within this holy sanctuary is a lit gold menorah and an ark with two cherubim facing each other on top, and the stone tablets inside: in this dwelling space of ourselves is the light of love for each other and love for G-d.
Meditation: Sit up straight and breathe deeply and relaxed. Feel the air fill up your lungs, and your abdomen expand to take it in. Become aware of the space within your body, and follow your breath so that your mind becomes more spacious. Let your thoughts flow with your breath and lower in volume as you follow the flow into your space. Let this space within your body and mind become a heart-space, a place where you can accept everything that comes into it. Breathe in and out a heartful acceptance of your present reality. Let yourself be spacious and open to your moment, loving it without expectation. Breathe in and out of your holy sanctuary.
