rgyu mtshan med pa'i yid dpyod

correct assumption lacking a reason; Comment: This is one of the three divisions of correct assumption (yid dpyod): correct assumption lacking a reason (rgyu mtshan med pa'i yid dpyod); correct assumption depending upon a counterfeit reason (rgyu mtshan ltar snang la brten pa'i yid dpyod); and correct assumption in which the reason is not ascertained (rgyu mtshan ma nges pa'i yid dpyod). There is also a division of correct assumptions into five: correct assumption whose reason is not established (rgyu mtshan ma grub pa'i yid dpyod); correct assumption contradictory with a reason (rgyu mtshan dang 'gal ba'i yid dpyod); correct assumption for which one has a reason but has not ascertained it (rgyu mtshan yod kyang gtan la ma phebs pa'i yid dpyod); correct assumption.
