The first 3 articles are from or about RABBI CHAIM VITAL (see "Dedication" below)
The 4th article presents insights for the first chapter of PIRKEI AVOT
(the Mishnaic tractate of 'Ethical Principles'), of which we study one chapter each Shabbat until Shavuot (and many repeat the cycle through the last Shabbat before Rosh Hashana).
The Weekly Reading combines two separate readings; these are the subject of the last three articles.
