'RChanina ben Chachinai says: One who stays awake at night or who travels on the road alone or who turns his heart to idle-ness, he bears guilt for his soul.

'RNechunia ben Hakanah says: Anyone who accepts upon himself the yoke of Torah [then] the yoke of government and the yoke of worldly responsibilities are removed from him. And anyone who throws off the yoke of Torah [then] the yoke of gov-ernment and the yoke of worldly responsibilities are placed upon him.
