Sāriputta answers Mahākoṭṭhika that ageing and death and the other links are neither made by oneself, nor by another, nor arisen by chance, but have their causes, consciousness and phenomenal objects leaning on each other like two sheaves of reeds. 12S2/1.7.7, translated from the Nidānasaṃyutta of the Saṃyutta Nikāya.
