Similarly, each person has leanings towards a different area. Some people are
more likely to be kind while others lean more towards strictness. Those whose soul is
rooted in kindness are more likely to learn Torah in a manner that will give spiritual
vitality to others, while those who are rooted in Gevurah are much quicker to establish
boundaries and make restrictive judgments. In addition, these souls are often drawn to
halachic stringencies. The Komarna Rebbe writes that generally the students of the Baal Shem Tov were rooted in the attribute of Chessed / Kindness, since their focus was
mostly on developing love of Hashem. (There were some notable exceptions, however.)
