Always be careful to rise at midnight. 1 He who does not rise, without having being prevented beyond his control, incurs a ban Above, Heaven forbid. 2

Convert the nights into days. Sleep a few hours during the day so that you will suffice with but little sleep at night. 3

When rising at midnight and overcome by sleepiness, drive it away by pacing back and forth in the house and chanting hymns with raised voice.

Study a number of [diverse] subjects. Do not concentrate on a single lesson lest it become onerous for you. Thus study many [different] lessons [and that will banish your sleepiness].
