Exceedingly sad is the blindness of the sons of men, who do not see the power and glory of the Lord. A bird lives in the forest, and does not see the forest. A fish swims in the water, and does not see the water. A mole lives in the earth, and does not see the earth. In truth, the similarity of man to birds, fish, and moles is exceedingly sad.
People, like animals, do not pay attention to what exists in excessive abundance, but only open their eyes before what is rare or exceptional.
There is too much of You, O Lord, my breath, therefore people do not see you. You are too obvious, O Lord, my sighing, therefore the attention of people is diverted from You and directed toward polar bears, toward rarities in the distance.
(Saint Nicolai Velimirovich, Prayers by the lake, chapter VII)
