A few quotes from the Rabbi on 'Israel and the Nations'
in which he teaches two stipulations: that a student be meek and that he study for the sake of learning.
"Then sang Israel this song: Spring up, O well, sing ye unto it". We know that the Torah is a spring of living waters and that this poesy refers to the Torah, as this indicates: 'Spring up, oh well' – to elevate the sparks of Torah, and this requires two conditions, which are: 'sing ye unto it'. The [Hebrew] letters of 'sing' [also] spell 'meek' – the Torah scholar should be meek, 'unto it' – and study for its own sake.
