The 18 Root Causes of Craving

Overview

The Buddha identified the exact psychological mechanism by which craving and ego-formation occur. The instant the mind makes the fundamental, delusional assumption “I am” (asmi), a cascade of eighteen specific internal psychological projections follows, creating the complex web of identity, desire, and anxiety. (Note: The sutta lists 18 internal and 18 external, making 36, but the core internal framework is 18).

The List

Dependent on the assumption “I am” (Asmīti sati), there arises:

1. “I am this.”
2. “I am otherwise.”
3. “I am bad.”
4. “I am good.”
5. “I might be.”
6. “I might be this.”
7. “I might be otherwise.”
8. “May I be.”
9. “May I be this.”
10. “May I be otherwise.”
11. “I shall be.”
12. “I shall be this.”
13. “I shall be otherwise.”
14. “I shall be possessed of form.”
15. “I shall be formless.”
16. “I shall be percipient.”
17. “I shall be non-percipient.”
18. “I shall be neither percipient nor non-percipient.”
