Heaven is a state we create between us in this life. That state is where we have built the right connections between us and made a place for the quality of bestowal to dwell and connection us together in love.
According to the above, we should interpret what _The Zohar_ says about the words, “If his offering is a burnt offering,” “for My thoughts are not your thoughts.” He says, “Also, the written Torah and the oral Torah, which is _Malchut_, were emanated from that thought.” We should interpret that in the work, _Malchut_ means “the kingdom of heaven,” which is faith, while “Oral Torah” is called Torah. In other words, it is impossible to be rewarded with the Torah if one has not been rewarded with faith, as our sages said, “It is forbidden to teach idol-worshippers the Torah.”

But there’s also this:
In spiritual attainment, the written Torah is accompanied by the oral Torah. The name “Torah” is derived from the word “Ohr – Light.” Thus, the written version of the book must be preceded by a preparation period, which is the oral Torah.
The oral Torah accompanies the written book and is transferred from one generation to another by word of mouth, from a Kabbalist to another Kabbalist. It is conveyed through a chain of people who are capable of understanding the book.
