Chasidut su Salmi 30:11

In hasidism, the path of avodah via imaginative thought [mahshavah] focuses on comprehension of supernal matters. This entails not merely performing mental combinations and yihudim of Names and letters, but also engaging in manifold thoughts of God’s greatnesses, which precedes His Names and their letters. [Further, i]t entails not merely thoughts of His greatness in the supernal worlds, but also of His greatness in this world, since an influx of holiness and revelation of His greatness is drawn into this world as well through the revelation of the Besht. Furthermore, ever since our sages drew forth and revealed the light in the vessels, the avodah of thought and apprehension focuses not only on kabbalistic matters, but also on the simple meaning of the Torah, of bartering animals and the like. It is true that the Zohar refers to the simple meaning of the Torah as sackcloth and its kabbalistic meanings as more minimal, purer garbing, in the sense of “You have removed my sackcloth…”³⁷⁹Psalm 30:11. Compare Zohar 3:152 for its privying of inner layers of meaning over the outer layers, akin to outer layers of clothing. Yet, now the vessels and sackcloth have become sanctified and are garbs of holiness, and great is the level of one who embraces the King even through his garb.
