Praiseworthy is the person who does not let a moment pass during these days without engaging in the service of Hashem or reflecting on teshuvah.  According to the holy Arizal, during these ten days one should conduct himself as on Chol Hamoed, limiting himself to only the most essential work, and spending the rest of the day meditating on teshuvah. Happy is the person who focuses his thoughts on G-d’s kindness and arouses people who are spiritually asleep, urging them to do teshuvah. ~ R’ Yonasan Eibes
