Viṃśatikā

The ‘Twenty Verses’, a key Yogācāra work by Vasubandhu which can be viewed as a companion to his Triṃśikā. The treatise discusses the nature of perceptual objects but interpretation of the text is controversial since it may be understood either as an ontologically orientated refutation of the existence of all external objects, or else in an epistemological sense which suggests that objects as they appear to the mind are merely contructs superimposed upon an indeterminate external reality. The work survives in Sanskrit as well as a Tibetan and two Chinese translations.
