The hand is the cutting edge of the mind. (Jacob Bronowski)

He sealeth up the hand of every man; that all men may know his work. (Book of Job, 37.7)

Length of days are in her right hand, riches and honour are in her left. (Prov. iii.16)  

Pale hands I loved beside the Shalimar,

Where are you now? Who lies beneath your spell?

(Laurence Hope, Kashmiri Song)

He Who made our hands still holds them. (Anon)
