The Culasaropama Sutra (Majjhima Nikaya #30) in addition to being an excellent teaching on the dangers of spiritual materialism, also refers to the Jhanas. However, it shows signs that suggest the text has been altered. Its beautiful mathematical harmony of the sutra suddenly breaks down in section 12 with a discussion of the Jhanas. The Jhanas are a concentration practice and concentration has already been stated in section 10 to be a lesser state than knowledge and vision. But when the Jhanas are introduced in section 12, they are said to be "higher and more sublime than knowledge and vision." The inclusion of the Jhanas here actually makes the sutta self-contradictory. It also contradicts other pro-Jhana sutras. The formulation of the eight Jhanas is the standard "short" one, (similiar to what is found in the Mahasatipatthana Sutta) but with the addition of a last sentence in each of the paragraphs: "This is a state higher and more sublime than knowledge and vision." This sentence directly contradicts the last sentence of section 84 of the Samannaphala Sutta (Digha Nikaya #2). In the previous paragraph of the Samannaphala Sutta, the recluse directs the concentrated, pure, bright mind resulting from the fourth Jhana towards knowledge and vision. The understanding gained "is a visible fruit of recluseship more excellent and sublime than the previous ones". Many other suttas show signs of this type of tampering and we are left today with the task of puzzling out the original teaching.
