金光明最勝王經疏 6.93

6.93

經　「時彼長者聞子請已，復以伽他而答之曰：『我今依古仙，所有療病法，次第為汝說，善聽救眾生。三月是春時，三月名為夏，三月名秋分，三月謂冬時。此據一年中，三三而別說，二二為一節，便成歲六時。初二是華時，三四名熱際，五六名雨際，七八謂秋時，九十是寒時，後二名氷雪。既知如是別，授藥勿令差。當隨此時中，調息於飲食，入腹令消散，眾病則不生。節氣若變改，四大有推移，此時無藥資，必生於病苦。醫人解四時，復知其六節，明閑身七界，食藥使無差。謂味界血肉，膏骨及髓腦，病入此中時，知其可療不。病有四種別，謂風、熱、痰癊，及以總集病，應知發動時。春中痰癊動，夏內風病生，秋時黃熱增，冬節三俱起。春食澁熱辛，夏膩熱鹹醋，秋時冷甜膩，冬酸澁膩甜。於此四時中，服藥及飲食，若依如是味，眾病無由生。食後病由癊，食消時由熱，消後起由風，準時須識病。既識病源已，隨病而設藥，假令患狀殊，先須療其本。風病服油膩，患熱利為良，癊病應變吐，總集須三藥，風熱癊俱有，是名為總集。雖知病起時，應觀其本性。如是觀知已，順時而授藥，飲食藥無差，斯名善醫者。』」

Sūtra: "Then that elder, having heard his son's request, answered him in turn with gāthās, saying:
'Relying now upon the ancient ṛṣis
and all their methods for curing illness,
I shall explain them to you in sequence;
listen well so that you may rescue sentient beings.
Three months constitute the spring season;
three months are called summer;
three months are called the autumn period;
three months are referred to as the winter season.
This is expounded distinctly in three-month units
with reference to a single year;
two by two they make one seasonal period,
thus completing the six seasons of the year.
The first two are the flowering season;
the third and fourth are called the hot period;
the fifth and sixth are called the rainy period;
the seventh and eighth are referred to as autumn;
the ninth and tenth are the cold season;
the latter two are called ice and snow.
Having come to know such distinctions,
dispense medicines without error.
In accordance with these seasons,
one must regulate food and drink;
when they enter the belly and are made to digest and disperse,
then the manifold illnesses will not arise.
If the seasonal energy changes,
the four great elements undergo shifts;
if at this time there are no medicinal supplies,
one will inevitably give rise to the suffering of illness.
A physician understands the four seasons
and also knows their six periods;
being clearly familiar with the body's seven dhātus,
he administers food and medicine without error.
These are the rasa-dhātu, blood, flesh,
fat, bone, and marrow and brain;
when illness enters into these,
one knows whether it can be cured or not.
Illnesses have four kinds of distinction,
namely wind, heat, phlegm,
and the illness of their combination;
one should know the times when they flare up.
In spring phlegm is stirred;
in summer wind illness arises;
in autumn bile-heat increases;
in the winter season all three arise together.
In spring eat astringent, hot, and pungent foods;
in summer unctuous, hot, salty, and sour foods;
in autumn cold, sweet, and unctuous foods;
in winter sour, astringent, unctuous, and sweet foods.
During these four seasons,
when taking medicine as well as food and drink,
if one relies on such flavors,
manifold illnesses will have no cause to arise.
Illness after eating is due to phlegm;
when food is digesting, it is due to heat;
after digestion, what arises is due to wind;
in accordance with these times, one must recognize the illness.
Having recognized the source of the illness,
one prescribes medicine according to the disease;
even if the symptoms are diverse,
one must first cure its root cause.
For wind illnesses, taking unctuous substances [is suitable];
for those afflicted with heat, purging is best;
for phlegm illnesses, one should induce vomiting;
for the combination, three medicines are required.
Wind, heat, and phlegm all being present:
this is called the combined [disorder].
Although knowing the time when illness arises,
one should observe their fundamental constitution.
Having observed and known in this way,
one dispenses medicine in accordance with the seasons;
when food, drink, and medicine are without error,
this is called an excellent physician.'"
