The heaviest tool in the Iranian house of strength is a pair of huge wooden shields — up to 220 pounds the pair — that you press upward off your chest while lying flat on your back, over and over, until you physically cannot continue.1 These are the sang — the word means "stones," because the originals were stone; the old name was sang-e zur, "stones of power."2 They build raw pushing strength, the "heavy sang, light mil" of the training-maxim — these are the brute-force tool, loaded heavy.
But the tradition gives the grinding press a startling spiritual reading. Some connect the sang to the Meccan pilgrimage rite of throwing stones at the devil: "When Muslims go on their pilgrimage, they throw stones against the devil... The stones are cast against a person's own ego, also considered to be the devil that lives within us. Therefore, the sang can represent the casting of stones against the ego."3 Every heavy press of the stone-shield, on this reading, is a stone cast against your own nafs — the devil-within, the lower self. The brute strength-exercise becomes a spiritual combat: you're not just pressing weight, you're driving stones against your own ego, the grinding repetition a war on the lower self.
Source trust note. From Billinge's War Yoga: Zurxāne (Sanctus Europa Press, an identitarian publisher). The sang, its construction, the "stones of power" name, the prostration ritual, and the press-variations are documented zurxāne practice (the Tumār-e Puryā-ye Vali is cited). The Mecca / stones-against-the-ego reading is the tradition's contemplative gloss, relayed as such. The page keeps the documented exercise and its ego-combat reading.
The sang are "wooden shields, which are pressed upwards while lying prone on the ground," considered "the 'first tool' of varzeš-e pahlavāni."4 Around 44 inches tall and 32 wide, weighted by thickness, a pair runs from 66 to 220 pounds. Their purpose is "to build excellent pushing and pressing strength, while in a state of motion, rather than in a static position" — they're shaped like flat shields with a perfectly balanced central handle.5
The practice begins with reverence: "the athlete prostrates in front of the sang, kissing the ground to show humility and gratitude to God," then lies prone facing the sky.6 Then the presses:7
The Scroll of Puryā-ye Vali notes the hard-ground principle here too: train "on the ground... hard, not soft. Because if it is hard, it hardens the body."8 And the sang specifically "require a grind mentality, which enables the [pahlavān] to push beyond his self-imposed limitations."9
The sang's deep mechanism is the conversion of brute endurance into spiritual combat — the grinding, to-failure press reread as the casting of stones against the lower self. This is the most demanding and least glamorous of the exercises (lying on your back pressing huge weights until you fail), and the tradition gives it the most pointed spiritual meaning precisely because of its grinding character.
The key is the grind mentality — the sang "require a grind mentality... to push beyond self-imposed limitations." The qaltān is done to failure, "until the athlete is no longer able to continue," the rep-count to exhaustion being the very measure. This is not the skilled control of the mil or the rhythmic attunement of the kabbāde; it's the pure grind — the willingness to keep pressing the heavy thing past the point where the lower self says stop. And that is where the ego-combat lives. The "self-imposed limitations" the grind pushes past are precisely the nafs — the lower self that wants to quit, that says enough, that imposes the comfortable limit. Every press past that limit is a stone cast against the ego, a refusal of the lower self's demand to stop, a small victory of the higher self over the devil-within.
So the Mecca-reading is not arbitrary decoration. The grind is the casting of stones against the ego because the grind is the overruling of the lower self's limit. The pilgrim throws literal stones at the symbolic devil; the pahlavān presses past the limit his own ego imposes, and each press past enough is a stone driven into the lower self. The brute, grinding, to-failure press is reread as the most direct spiritual combat available — not the subtle attunement of the contemplative but the raw, grinding overruling of the ego's stop, the higher self winning ground from the lower one press by press. The heaviest, least glamorous exercise carries the most direct ego-combat, because the grind past the self-imposed limit is the war on the nafs made physical.
This page details the strength-tool and its ego-combat reading:
For the Indic limb, the sang is the cognate of the gar nāl (the stone-ring of pain) and the nāl (the pressing-stone) — the heavy stone-tools of the akhara whose grinding work is read as spiritual. The "grind mentality" and the ego-combat reading rhyme directly with the Indic mehnat (grueling work as devotion) — the akhara's teaching that the brutal, grinding labor is the offering, the press past the limit is the worship. Both traditions make the heaviest, most grinding work the most directly spiritual, because the grind past the ego's stop is the clearest victory over the lower self.
Notice the two different press-counts: the jofti (double press) is done seventeen times — a fixed number — while the qaltān (turning press) is done to failure, "until the athlete is no longer able to continue," the count being the score. This contrast is worth deconstructing, because it encodes two different relationships to the limit.
The fixed seventeen is measured strength — the controlled, disciplined dose, the press done a set number of times regardless of how you feel. The to-failure qaltān is maximal strength — the press taken to the absolute limit, the ego's stop overruled until the body itself fails. The tradition uses both: the measured dose (discipline, control, the right amount) and the to-failure grind (the war on the self-imposed limit). And it's the to-failure one that's scored — the competition measures not the controlled seventeen but the grind to exhaustion, because that's where the ego-combat is, where the "self-imposed limitations" are pushed past, where the stones are cast against the nafs.
The case reveals a sophisticated understanding of the limit. There's a measured relationship to strength (the disciplined seventeen — know the dose, do it controlled, don't grind everything) and a maximal relationship (the to-failure qaltān — find the limit, push past it, war on the ego's stop). A complete practice needs both: the measured discipline that builds steadily and the to-failure grind that breaks the self-imposed limit. And the deepest spiritual work — the casting of stones against the ego — happens specifically in the to-failure grind, where you discover that the limit your lower self imposed (enough, stop, I can't) was self-imposed, and you press past it, and the stone goes into the devil-within. The seventeen builds strength; the to-failure grind builds the man who can overrule his own ego's limit — which is the harder and more important thing.
You hit limits — points where something in you says enough, stop, I can't — and you've taken those limits as real, as the edge of your capacity. The sang teaches a different relationship: many of those limits are self-imposed by the lower self, and the grinding press past them is a direct war on the ego, each push past enough a stone cast against the devil-within.
You learn to distinguish the measured work from the to-failure work, and use both. Most of your discipline is the measured seventeen — the controlled, dosed, sustainable effort that builds steadily without grinding everything to exhaustion. But you also, deliberately, do the to-failure grind — the work taken past the point where the lower self says stop, where you discover that the limit was self-imposed and you can press beyond it. And in that grind, you do the ego-combat the tradition names: you treat the lower self's stop not as the truth about your capacity but as the nafs imposing its comfortable limit, and you cast a stone against it by pressing past — not recklessly (you respect real limits, real injury) but past the ego's limit, the I'd-rather-not, the comfortable enough. Each press past the self-imposed limit is a small victory of the higher self over the lower, a stone driven into the devil-within.
And you keep the reverence the sang frames it with. The pahlavān prostrates and kisses the ground before pressing the stones — the grind is preceded by humility and gratitude, not bravado. So your to-failure work, too, is held in reverence: not the ego's grinding to prove itself (which is the nafs in disguise) but the higher self's humble war on the lower, the grind offered rather than flaunted. The casting of stones against the ego is only spiritual combat if it's the higher self overruling the lower — and the prostration before the grind is what keeps it from becoming just the ego grinding to feel strong. You bow, then you press past the limit, and the press is a stone against the self that wanted to stop.
The sang fails in two opposite ways. The grind as ego is the most insidious: the to-failure grinding done by the lower self to prove itself — the bravado, the showing-off of endurance, the ego grinding to feel strong, which is the nafs wearing the costume of spiritual combat. The diagnostic sign is the grind done in pride rather than reverence, to impress rather than to overrule the self — the prostration skipped, the humility absent, the stones cast for the ego rather than against it. This fails because it inverts the whole point: the grind is supposed to be the higher self warring on the lower, and if it's the lower self grinding to aggrandize itself, the stones are landing on the wrong target. The limit taken as real is the opposite failure — accepting the lower self's stop as the truth about one's capacity, never doing the to-failure work, never discovering that the limit was self-imposed. The diagnostic sign is the comfortable enough, the limit never tested, the ego's I can't believed. This fails because it leaves the nafs in charge — its self-imposed limits unchallenged, its stop obeyed, no stones ever cast against it. The corrective for both is the framing the sang provides: the reverence (prostration before the grind) that keeps the grind from being ego, and the grind itself (to-failure, past the self-imposed limit) that keeps the ego's stop from being obeyed. The right sang-work is the humble higher self pressing past the lower self's comfortable limit — reverent and relentless at once, the stones cast against the ego by the self that bowed before it pressed.
This is descriptive of documented practice. The Mecca / stones-against-the-ego reading is the tradition's own contemplative gloss (relayed by Billinge, "some say"), which the vault keeps as the practice's self-understanding rather than an endorsed metaphysical claim. The convergence with the Indic mehnat (grueling work as devotion) and the gar nāl/nāl stone-tools is the notable cross-tradition link — both make the heaviest grinding work the most directly spiritual. The "grind mentality / push beyond self-imposed limitations" is consistent with the corpus-wide character-forging-through-the-body principle.
Plainly: the grinding press past a self-imposed limit, reread as a war on the lower self — and the distinction between the grind that overrules the ego and the grind that is the ego — is a mechanism psychology and behavioral-mechanics both reach for.
The Sharpest Implication. Many of the limits you take as the edge of your capacity are self-imposed by the lower self — the comfortable enough, the protective I can't — and the grinding press past them is a direct war on your own ego, each push past stop a stone cast against the devil-within. But the same grind can be the ego itself in disguise — bravado grinding to prove itself — and the only thing that keeps the stones landing on the right target is the reverence that bows before it presses. The grind past the limit is spiritual combat only when it's the humble higher self overruling the lower, not the lower self grinding to feel strong.
