The schema of the three turnings is found in Yogachara and Tathāgatagarbha texts such as the Saṃdhinirmocana Sūtra and the Srimala Sutra and likely originated in the Yogachara literature. Naturally, they identify themselves as definitive. However, the schema was later adopted more widely, and different sects and schools of Buddhism, as well as individual Buddhist teachers and philosophers give different explanations as to whether the second or third turnings is 'definitive' (Skt: nitartha ) or 'provisional' (Skt: neyartha ) or requiring interpretation. In the Tibetan tradition, the Gelug school considers the second turning definitive, as do some scholars in other schools.
General Motors issued a pair of recalls for the C5 Chevrolet Corvette (1997-2004 models) due to problems with locked steering. In addition to being locked while starting, owners complained that in some cases their cars could be driven but with no control of steering. This problem is due to a lock pin that fails to withdraw fully, allowing contact between the pin and lock plate. Visit the National Highway Traffic Safety Administration (NHTSA ) website (see Resources) for information about recalls #04006B and #04006C or call your Chevrolet dealer.
