In the heaven state the fulfillment of desires is not, as in the gross sphere, dependent upon having the object of desire. Fulfillment of desire comes merely through thinking of the object desired. For example, if a person wishes to hear exquisite music, he experiences this pleasure merely by thinking about it. The imaginative idea of exquisite music becomes, in this state, a substitute for the physical sound vibrations in the gross sphere. The pleasure he derives from the thought of exquisite music is much greater than the pleasure he derived in his earthly career from the actual hearing of physical sounds. In the heaven state there are no obstacles between desires and their fulfillment; the pleasure of self-fulfillment through thought or feeling is always at hand.
