Furthermore, an Āgama sūtra states: “There are four causes and conditions for gray hair: first, an excess of fire; second, an excess of worry; third, an excess of illness; fourth, premature graying in one's family line. There are four causes and conditions for a person's illness and emaciation: first, eating little; second, having anxiety; third, frequent sorrow; fourth, having an unharmonized illness. There are four matters that do not give prior notice to a person: first, gray hair; second, old age; third, illness; fourth, death. These four matters can neither be avoided nor repelled. All flavors do not exceed eight kinds: first, bitter; second, astringent; third, pungent; fourth, salty; fifth, bland; sixth, sweet; seventh, sour; eighth, indeterminate flavor.”
