Now gain is of three kinds, viz.: gain of wealth, gain of religious merit, and gain of pleasure; and similarly, loss is of three kinds, viz.: loss of wealth, loss of religious merit, and loss of pleasure. At the time when gains are sought for, if other gains come along with them, these are called attendant gains. When gain is uncertain, the doubt of its being a gain is called a simple doubt. When there is a doubt whether either of two things will happen or not, it is called a mixed doubt. If while one thing is being done two results take place, it is called a combination of two results, and if several results follow from the same action, it is called a combination of results on every side.
