The spiritual world is not in a different dimension or up in the clouds. It is something you find inside your attitude to other people, when you see that your neglect toward them becomes replaced by attentiveness toward them and a feeling that they are important. This happens because you wish to reach spirituality, and you start to see that they are your partners on this path.
You then begin to worry about them and to take care of them just as you would with anyone who is important to you. At first you do this egoistically, but you gradually start to feel that you want to give to them.
That is when the Light begins to work, making you feel that there are qualities inside you that you have to correct. You wish to treat others with love, and you also feel that only the Light can carry out this correction. If you really want this to happen, then the Light will come and correct you.
However, this Light works only inside the connection between people, turning hatred into love and correcting the breaking which once turned love into hatred. Inside this new attitude to others, you begin to reveal the spiritual world that was lost during the breaking. You realize that your connection with others is a connection of souls, of your inner desires, and inside it, you reveal the Creator.
All of this occurs precisely inside this net of desires that bind all of you. They create a vessel (Kli), in which your spiritual life becomes revealed. Meanwhile, the material life turns out to be but a dream, like an imagined world.
Deep inside the connection among people, you reveal the quality of bestowal, and you realize that it is the only thing that exists in the world. Everything else was a fantasy, a concealment of the spiritual world, which was necessary in order for you to reveal it.
