Your knees are your wings.
On the other hand, when someone tries to take worship back into the purely spiritual realm and refuses to give it embodied form, the act of worship evaporates, for what is purely spiritual is inappropriate to the nature of man. Worship is one of those fundamental acts that affect the whole man. That is why bending the knee before the presence of the living God is something we cannot abandon.
--Joseph Ratzinger (Pope Benedict XVI), The Spirit of the Liturgy (189-93)
I [...] fell upon my knees and spread out my hands to the Lord my God.
