On the topic of 'early to bed and early to rise', I'd like to share the following vort I once saw in a Chassidic sefer:
Ad mosai otzail tishkav, mosai tokum mishnosecho (Mishle 6:9)
Poshut pshat applies to getting up in the morning:
Ad mosai otzail tishkav? - How long will you lie in bed, you lazybones?
Mosai tokum mishnosecho? - When will you arise from your sleep?
But we can apply it to going to bed in the evening:
Ad mosai otzail? - How long will you lazy around?
Tishkav! - Go to sleep already!
Mosai tokum mishnosecho? - When will you arise in the morning if you go to sleep so late?
Which reminds me of another Chassidic vort on this topic:
Shulchan Aruch begins "Yisgaber ko'ari" - one must be strong as a lion to get up in the morning for service of Hashem. Then it says, "also when he lies down in bed he should realize before whom he is lying..." And the kashya is, after discussing the getting up routine, why does he regress to the going to sleep routine? And the answer is, because if one goes to sleep as a 'ferd' (horse) he cannot get up as a 'laib' (lion).
So it is not only important to go to sleep 'early' - it is even more important to go to sleep 'holy'.
Hatzlacha
