Answer: We constantly talk about this in our daily lessons.
In order to sense the upper world we need to build a sensory organ, in other words, a vessel of reception.
We must build this vessel from the egoistic desires of the ten (ten people) so that it becomes a sum of all our good qualities that are directed toward bestowal and love.
To do this, we must rise above ourselves, correctly interacting with each other in order to connect our ten points in the heart.
If we succeed, we will turn into the quality of bestowal and love and will become an instrument for reception.
Then all the Upper Light that is around will fill us. This upper field will be called the Creator.
Therefore, we need to build a vessel of the soul into which the Light of the soul enters.
