Musar zu Jirmejahu 41:9

Behold the story of Gedalia ben Achikam where it is clear to our eyes that due to his great Chasidut to not judge Yishmael ben Netanya negatively, nor to accept an evil report, he said to Yochanan ben Kareach "you are speaking falsely of Yishmael" (Yirmiyahu 40:16). What resulted from this? He was murdered, the Jews went into exile, and their last ember was extinguished. Scripture attributes the murder of these people as if Gedalyah himself murdered them, as our sages of blessed memory, said (Nida 61a) on the verse: "all the bodies of the men whom he had killed through Gedaliah" (Yirmiyahu 41:9).

And when he contemplates G-d's great lovingkindness to us, His great love for the Jewish people, the closeness of the Just to Him, the virtue of Torah and mitzvot, and other similar investigations and studies, certainly, a powerful love will ignite within him, and he will choose and lust to cling to Him. For when he sees that the Creator, blessed be He, is literally (mamash) like a father to us, and has mercy on us as a father on his sons, there will then awaken within him a desire and longing to reciprocate back to Him, as a son to his father.

For this, a person must seclude himself in his chambers, and focus all his knowledge and thought to the observation and in-depth study of these true matters.
