Chasidut על אבות 1:18

Since there is in the mishnah "on three things the world stands on Torah, and on Service and on Acts of Loving Kindness" (Avot 1:2) and there is in the mishnah "on three things the world stands, on Judgment, and on Truth and on Peace" (Avot 1:18). And we can also say that they have the same intention, that behold we are presented with three levels in the service of the High Creator, one - Torah learned for its own sake, and in truth our sages of blessed memory allowed us [study of Torah] even not for its own sake, as they said "a person should always engage etc" even if one does not reach to the levels of learning for its own sake nevertheless you should not refrain from it, since it is not quickly that one attains to learn for its own sake, but through a great exertion in one's service to the Blessed Name with all the good personal qualities.

And let us return to the first issue, "on three things the world stands, on judgment [din]" (Avot 1:18) - this is Torah, as there is that Torah is also called judgment in whichever way it will be, as explained above [for its own sake or not]. "And on truth" - that is the level of Yaakov, that is the average, that is compassion [rachamim], as it is written 'gave truth to Yaakov' (Micah 7:2) that through the raising of the holy sparks one awakens compassion and there is no need for lovingkindness, as explained above. "And on peace"- that is clinging to God, that one clings to the Blessed Creator since the name of the Holy Blessed One is Peace (Tractate Derekh Eretz Zuta, Section on Peace 11).
