 The main Buddhist schools represented in his works are the Vaibhāṣikas or Sarvāstivādins of Kashmir and Gandhāra, the Vātsīputrīyas, the Sautrāntikas (also called Dārṣtāntikas), and the Yogācārins. He also argues with non-Buddhist, Orthodox (Hindu) positions, including especially Sāṃkhya and Nyāya-Vaiśeṣika views. It would appear that the only Buddhist school with which he always expresses disagreement is the Vātsīputrīyas, also called the Pudgalavādins or “Personalists.” Vasubandhu’s works are most often said to have been written either from the Sautrāntika perspective or from the Yogācāra perspective, depending upon the work. Yet the verses of his Treasury of the Abhidharma summarize the doctrines of the Kashmiri Vaibhāṣika school. It is only in the commentary that the Sautrāntika system tends to win the day, through numerous  arguments.[10]  And, it is quite often the case, even in the Commentary, that Vaibhāṣika views are left unchallenged or unharmed.
