Man is not only spirit and mind but he also has corporeal senses which should sense the cross through the above-mentioned means
Not all people are of the same spiritual level and do not need the senses for their spiritual contemplation. The senses are nourished by all the above-mentioned means and are not confined within themselves but they transfer the effects they receive to the mind and the spirit. The mind by itself might not remember the cross or might not remember it much. But when it perceives the cross before it, through the senses, it remembers all the divine and spiritual feelings connected with the cross and the Crucified. Thus we worship God spiritually, intellectually and physically. All these strengthen each other.
