Among them, 'combination' is the joining together of two or many substances.
It initiates a distinctive effect that the substances do not have individually.
'Preparation', on the other hand, is produced by contact with water or fire, purification, churning, place, time, steeping, vessel, and so forth.
'Measure', again, is the mass of food, considered collectively as the bulk measure and with respect to each individual substance.
'Place' refers to the origin and habitat of the substance and the consumer.
There, moreover, the consumer is to be examined through his state of being healthy or sick, and by variation of constitution.
And likewise whoever sees a distorted form perishes.

even upon its depletion, vāyu, drawing fat and the other bodily tissues that constitute the supreme essence of the body to the bladder, discharges them along with urine.
