Avodah Shebelev (עבודה שבלב) — The Service of the Heart
Core definition
Avodah shebelev — "the service of the heart" — is tefillah (prayer). The identification is scriptural: "u'le'avdo b'chol levavchem" (Devarim 11:13) — "what is the service of the heart? This is prayer" (Taanis 2a). In the corpus, prayer as avodah shebelev is "the language of joining from below upward" (the ladder): toward the Etzem no avodah applies, so Havayah (sovev) must be drawn into Elokeichem — through avodah shebelev, tefillah [58837/maamar_066 :: §1021].
How the Rebbeim develop it
The four levels of tefillah. The maamar of 58837 maps prayer's ascent in four rungs: hoda'ah (acknowledgment); pesukei dezimra, the level of ruach; Kri'as Shema, the bitul of the mochin; and Shemoneh Esrei, bitul atzmi. Through them the embodied soul is joined with its root; and above, tefillah elevates Malchus — "va'ani sefilah" [58837/maamar_066 :: §2510]. The battle-character of this joining is explicit elsewhere: "the time of prayer is the time of battle" — the war between the yetzer hara (darkness) and the yetzer tov (light) is fought in davening [19800/maamar_012 :: Overview].
The heart's inner work. "Both in the service of the heart: in the love and awe themselves — 'aseh retzono': that he reach the aspect of the Divine light — the aspect of the will, which is the light's revelation" [15911/maamar_012 :: §216–218]. The heart's service is thus the cultivation of ahavah and yirah themselves, reaching the divine will's revelation.
The historical shift. One maamar marks an era-change: "in the time of the Beis HaMikdash they were possessors of da'as and lofty brains, and all their avodah was in the avodah of the brain; and now it is in the avodah of the heart — the avodah in deed, in actual practice; in every thing they do it is through mesirus nefesh" — and precisely therefore "it is easier to reach this bitul" [15962/maamar_007 :: §417–422]. The heart's service in exile carries the mesirus nefesh that the brain's service in the Mikdash era lacked.
The mixed character of prayer. "In good there is a mixture of evil: as in the avodah of the heart in prayer — praying in his heart with love and fear" — yet the mixture does not disqualify the avodah; the heart's service is the arena where the nefesh haElokis's vitality contends with the nefesh habehamis's strange thoughts, until "the sudden heartfelt outcry from simple faith and hope" breaks through [15966/maamar_011 :: §625; 19800/maamar_012 :: Overview].
Key distinctions
Avodah shebelev vs. avodas hamoach. The brain's service (Mikdash era) vs. the heart's service (now): the heart's service is deed in actual practice through mesirus nefesh, and reaches bitul more readily [15962/maamar_007 :: §418–422].
The four rungs. Hoda'ah → pesukei dezimra (ruach) → Kri'as Shema (bitul of mochin) → Shemoneh Esrei (bitul atzmi): an ascending scale of nullification, joining the embodied soul to its root and elevating Malchus [58837/maamar_066 :: §2510].
"Es" (alef to tav). In the verse's reading, "es" elevates the world of dibbur — the heart's service works through speech, the ladder's rungs [58837/maamar_066 :: §2510].
