2. Bíja Sutta. Just as earth is essential to all seed and vegetation, so is virtue essential to the practice of the Noble Eightfold Path. S.v.54f.
3. Bíja Sutta. Perverted view is the most fertile soil for the development of evil states. A.i.30.
4. Bíja Sutta. Just as bitter seed produces bitter fruit, so do false views produce evil and suffering. It is the opposite with sweet seeds and right views. S.v.212ff.
