To stop them sucking milk of that sublime knowledge.

Context

“The devotee of seven hundred thousand years (Satan) Was made a muzzle for that yearling calf (Adam) , 6 Lest he should suck milk of the knowledge of faith, And soar on high even to the towers of heaven. The knowledge of men of external sense is a muzzle To stop them sucking milk of that sublime knowledge. But God drops into the heart a single pearl-drop Which is not bestowed on oceans or skies!" "How long regard ye mere form, O form-worshippers? Your souls, void of substance, rest still in forms. If the form of man were all that made man,” source
