Likutei Moharan 169:3/ליקוטי מוהר"ן קס״ט:ג׳

13. And this is [the explanation of the opening verse]: {“And it will be in the wake of your listening to these laws, safeguarding and doing them….”} V’hayah (And it will be) ekev (in the wake of) your listening—“V’hayah” connotes joy; “ekev” alludes to the feet. That is, to be worthy of joy—to the point where the EKEVayim (the heels), which are the feet, hear the joy—this is achieved by:

2these mishpatim (laws), safeguarding and doing them—You should safeguard doing the mishpatim (evaluations) and judgments by yourselves. Through this, the judgment from Above is eliminated, as mentioned.

3Then, “V’hayah ekev your listening.” You will hear the joy in the feet, as a result of the judgments having departed from there.
