The Holy Temple had one altar in the outer part of and one in the inner part. The smoke from the outer altar has the aspect of Malchut and the cloud of the incense (Ketoret) from the inner altar has the aspect of Zeir Anpin. When the two meets they connect Chokmah and Binah that make Da’at (Da’at means Knowledge). When Da’at is formed by Chokmah and Binah the Light can flow to Malchut through the six sefirot of Zeir Anpin.
The Zohar says that the vapor from the mouth of those who study the Torah is like the smoke that comes from the burnt offerings. It has the aspect of Malchut. The warmth of the vapor comes from the heart that is the aspect of Zeir Anpin.
The heart is the aspect of Zeir Anpin. It represents the consciousness of the one who study the Torah in its inner levels. Zeir Anpin, the ‘heart’, goes up to unify Chokmah and Binah, connect itself to Da’at (Knowledge) and activate the central column to accept the flow of Light from above to below.
Because of its inner levels, the Zohar like the Ketoret in the inner part of the Holy Temple elevates us to Chokmah and Binah to open the channel of knowledge to the world. Those who study feel the greater understanding and awareness to their environment many times fold that before they started studying the Zohar.
It is beneficial to burn incense while studying. I suggest Indian brands because I believe that they won’t use any animal by products in the making of incense.
One of the prayers that Rabbi Shimon give great importance is the story of the Ketoret (incense). He said in the Zohar that if people would understand the value of it, they would put it in gold letters on their foreheads.
There are great benefits for those who reads it from a parchment written by a Sofer (Torah scribe). Those who pray daily and wish to have the Ketoret on parchment, I can connect them with a great sofer that can write it especially for them. Only Jewish men/converts can use it because it’s like a Torah scroll. It cost $$$. Email me for details. It takes time to write it so there’s no rush service.
