"Sh'ma Yisrael" and 'Blessed be the Name'
When the children of Yisrael are declaring the union of the secret of Sh'ma Yisrael, we learn, one light emerges from concealment in the upper world. This light is then battered into a 'hard spark,' which itself is finally divided into seventy lights. These are illuminated in the seventy branches of the Tree of Life, and the Tree emanates fragrance and gives forth spices. At the same time, all the trees in the Garden of Eden emanate fragrance and praise their Master. All the supernal limbs, the Sfirot, join in one aspiration and one desire to be unified as one without any separation.
Following this, we learn of the secret and joyous mating of Malchut, the Queen, with Zeir Anpin, and are told of the significance of the four keys, and of the four letters on them, which when they are gathered together cause the union. The union above, we learn once more, is mirrored by the union below. It is not possible to refer openly to Malchut as 'one' - in case the evil eye is aroused - but in the time to come, the Other Side will separate from her, and will in fact be removed from the world. Then, and only then, will Malchut be called 'one.' By her union to Zeir Anpin in silence and in secret, though, she is now removed from that Other Side.
The secret of the upper world, we are then told, is the heart of Jacob, and the secret of the lower world is the heart of his sons. Rabbi Hamnuna Saba (the elder), we discover, has said that the awakening of this union between Malchut and Zeir Anpin is beautiful. Lastly, we are reminded there is a commandment to study the Torah every day. The Torah is the Tree of Life, and he who studies it deserves to be bound with the supernal Torah.
The Zohar ignites the seventy Lights that illuminate the seventy branches of the Tree of Life by revealing holy secrets pertaining to the Tetragrammaton .י.ה.ו.ה. This Light conjoinsMalchut (our world) with Zeir Anpin (upper world), our body with our soul, which now elevates us above and beyond the sphere of influence of the Other Side.
