This is primarily a ל”ג בעומר Ma’amar.
בחוקותי means תורה that results in a physical change in the world as it says ונתתי גשמיכם בעתם the Torah that makes it rain is the level of רבי שמעון בר יוחאי.
This is, of course, the story in זהר where through תורה ושבחים of רשב”י it rained.
The Ma’amar discusses the difference between תורה ותפילה which are מלמעלה למטה and מלמטה למעלה and the way they affect the physical world.
The idea of דירה בתחתונים through (קריאת שמע and) מצוות is also explained.
The last idea is that the שבחים of רשב”י reveals something higher than his תורה: the level of מלך which is higher than רב. MP3
