Fasting is of two kinds: a. itvara, temporary, and b. maranakâla, fasting which precedes, and ends with death. Temporary fasting is either such in which a desire (for food) is present, or such in which no such desire exists. (9) a. The temporary fasting is briefly of six kinds: 1. in the form of a line; 2. in the form of a square; 3. in the form of a cube; 4. of a sixth power; 5. of a twelfth power; 6. of any arrangement. Temporary fasting (can be practised) for different objects which one has in mind. (10, 11) b. Fasting which is to precede death, is of two kinds with regard to the motions of the body: with change (of position) and without change. (12)
And again it is twofold: admitting of relief, or not; one may either leave the place (which one has chosen to die in), or not leave it; in both cases one may not take any food. (13)
