To reveal the spiritual world means to enter a new realm, where our usual organs of perception do not work, and we have to develop them in a totally new way. Spiritual perception is above our desire to receive, to feel, to enjoy. Spiritual “organs of perception” work in the opposite way - in bestowal, in the pleasure of fulfilling another. The transition from the perception of our world into the perception of the Upper world lies in crossing the Machsom. When a person changes his animate perception (taste, touch, smell, etc…) to its opposite spiritual perception of the world. Moreover, the more he develops these new “organs of perception”, the more he attains reality in its true form, not distorted by our egoistic “veil”.
