Ever since the later Indian Yogācāra school was founded by Dharmakīrti(600-660 C.E.), it has exerted a strong influence upon Indian philosophy. The treatises of this school were written to prove the essential thoughts of Buddhism as well as to refute the main ideas of Hinduism and Jainism. The topics of refutation are the theories of ātman and īśvara and so forth while those of proof are the theories of momentariness and sarvaja and so on. Yogic intuition(yogijāna, yogiprayakṣa) is a key concept to prove the omniscience(sarvajatā) attributed to the Buddha. It arises through the practice of meditation on the Four Noble Truths. As a sort of perception, this cognition is free from conceptual construction and is non-erroneous. In medieval India, yogic intuition was a central topic in debates between Buddhists and their Hindu opponents. This paper deals with yogic intuition from the perspective of debate. It investigates how the Mimāṃsākas and the Naiyāyikas raise issues with regard to this concept and how the later Indian Yogācārins refute them and prove their own views. Especially, this paper introduces the following two controversies: 1)How does yogic intuition fulfill the two conditions of perception, which are freedom from conceptual construction and non-erroneousness? 2)How is the intensification of meditative practice possible even though every existence is momentary?
