In the night of weariness
let me give myself up to sleep without struggle,
resting my trust upon thee.
Let me not force my flagging spirit into a poor preparation for thy worship.
It is thou who drawest the veil of night upon the tired eyes of the day
to renew its sight in a fresher gladness of awakening.
Rabindranath Tagore
