The article represents the capsule review of the ontological constructions of the main trends of the Buddhist Philosophy: Sarvastivada, stating that only dharmas are real; Yogachara with its absolutization of the role of consciousness; Madhyamaka with its doctrine of the ineffability of reality. The article critically examines the statements of various modern researchers, such as Karunadasa, F. I. Scherbatskoy, J. Singh, and ancient philosophers, such as Vasubandhu and Nagarjuna, on the ontological problematics.
