俱舍論疏 28.18

28.18

The Śāstra says: "Other masters say [...] namely, the four dhyānas." This states the doctrine of the Sautrāntika master. This master cites a sūtra stating that the training in concentration is the training in the higher mind, and stating that the four dhyānas are the utmost purity of mind, to prove that concentration is just the mind itself.
