Spiritual Tools: Kav ha-Yashar: Perfection Through Torah Study
The 15th of Adar is the Yahrtzeit of Rav Zvi Hirsch (ben Aharon Shmuel) Kaidanover of Vilna and Frankfurt (1712). The son of the Birkas Shmuel, he himself was the author of Kav Hayashar, a sefer which Reb Elimelech of Lizensk learned through 102 times.
“The Torah of God is perfect, restoring the soul (Psalms 19:8).” When God grants permission to a soul to explain a verse according to the understanding of his soul, it is a spark as from a rock struck with a hammer; a spark from something whole and perfect, the Torah, which speaks to every part of the body. Even if he is incomplete, that spark attaches him to perfection, and it is a spark of perfection that ignites his entire being to reach up to the Highest Heaven and attach to its creator.
Can be used as a Kavanah for Pesukei d’Zimrah of Shabbat and Yom Tov.
