As Guang Xing points out though, the origin of these Mahāsaṃghika doctrines can be traced to various passages in the nikayas -- and particularly suttas such as MN 123 and Snp 3.11, which clearly present the Buddha as a world-transcending, magical being. Not to mention numerous references in the suttas to supranormal powers and conversations with gods and devas, and the assertion in DN 16 that the Buddha could extend his lifetime to last an entire kalpa.
