Very often people make an effort - but in vain - to awaken a friend or a near relation whom they love. But in the first place we do not know if that person is not more awakened than we ourselves, and we may be trying in vain. And the other point is that a person may be asleep and needs that sleep. Waking him would be a sin instead of a virtue. We are only allowed to give our hand to the one who is turning over in his sleep, who desires to awake. Only then a hand is given.
