The commandment to walk in - and make oneself similar through - the ways of God, may He be blessed: That we were commanded to perform all our actions in the way of straightness and goodness with all our strength and to incline all our affairs that are between ourselves and others towards the way of kindness and mercy; as we have known from our holy Torah that this is the way of God, and this is God’s desire for His creatures so that they merit God’s goodness - as He desires kindness. And about this is it stated (Deuteronomy 28:9), "and you shall walk in His ways." And this commandment was further repeated in another place, as it is stated (Deuteronomy 10:12, 11:22), "to walk in all His ways."
(א) יסוד החסידות ושרש העבודה התמימה הוא שיתברר ויתאמת אצל האדם מה חובתו בעולמו ולמה צריך שישים מבטו ומגמתו בכל אשר הוא עמל כל ימי חייו.
(1) The foundation of piety and the root of perfect service [of G-d] is for a man to clarify and come to realize as truth what is his obligation in his world and to what he needs to direct his gaze and his aspiration in all that he toils all the days of his life.
בראשית רבה י'
אָמַר רַבִּי סִימוֹן אֵין לְךָ כָּל עֵשֶׂב וְעֵשֶׂב, שֶׁאֵין לוֹ מַזָּל בָּרָקִיעַ שֶׁמַּכֶּה אוֹתוֹ, וְאוֹמֵר לוֹ גְּדַל
Medrash Bereishit Rabbah 10
[every blade of grass has] a mazal that strikes it and says to it, ‘Grow!’
(כד) לבשר אחד הַוְּלָד נוֹצָר עַל יְדֵי שְׁנֵיהֶם וְשָׁם נַעֲשֶׁה בְשָׂרָם אֶחָד (שם נ"ח):
(24) לבשר אחד ONE FLESH — Both parents are united in the child.
