Gārava: Reverence
Reverence is the weight one gives to what deserves it. Coming near is the whole risk in this scene: the closer the ground, the more careful the step, the way you slow as you approach a fire. Aaron's sons walked in with their censers and none of that weight, and the nearness they took lightly consumed them.
Appamāda: Heedfulness
Heedfulness is care that does not lapse. Strange fire in a censer is the work of one unwatched moment, like a foot placed wrong at the top of a ladder. Where the ground is holy, attention has to run continuously, and being shown holy by those who come near is another way of saying that the approach itself must be watched.
Ottappa: Dread of doing harm
Ottappa is the shrinking back from wrongdoing, felt with others in view. Being glorified before all the people means nothing at that altar was ever private: the camp watched two priests improvise, and the camp watched what came of it. Serving in open sight puts a second weight on every motion of the hands, and that weight is what steadies them.
Saṃvega: Urgent shock
Saṃvega is the jolt that a death delivers to the living. Two young men were offering incense an hour ago and are now being carried out of the camp by their tunics, and their father is looking at it. Everything that felt solid, the family, the office, the ritual he knew by heart, has gone out from under him, and a shock like that burns off the routine and leaves only the question of how to stand now.
Adhivāsana: Patient bearing
Bearing of this kind takes what has come without pushing back at it. Aaron has lost two sons in one morning and mourning is closed to him: no torn clothes, no loosened hair, the grief with nowhere outward to go. He carries it upright, the way a man holds a heavy load he has no place to set down, feeling all of its weight and fighting none of it.
Tuṇhībhāva: Silence
Silence in the trained sense is a mouth at rest. Aaron held his peace, and there is no argument in it, no defense of his sons, no question put to Moses or to Yahweh. Whatever moved in him stayed where it was, and that stillness is his answer to what he has just been told.
