俱舍論頌疏論本 16.83

16.83

The explanation says: Four conditions must be met to constitute the course of action of false speech: 1. Uttering words with a contrary notion toward the object regarding which one deceives, such as saying one did not see when one saw. 2. The one deceived understands the meaning of what was said, being in mutual comprehension. 3. Arousing a defiled mind. 4. Being without error. The first three are present in the verse; "without error" carries forward from the preceding. If the one deceived does not understand the meaning of the words, it is subsumed under frivolous speech and does not constitute the course of action of false speech.
