On one occasion the Blessed One was dwelling at Rajagaha in the Bamboo Grove, the Squirrel Sanctuary. Then the Venerable
Samiddhi approached the Blessed One … and said to him: “Venerable sir, it is said, ‘Mara, Mara.’ In what way, venerable sir, might there be Mara or the description of Mara?”
“Where there is the eye, Samiddhi, where there are forms, eye-consciousness, things to be cognized by eye-consciousness, there Mara exists or the description of Mara.
“Where there is the ear … the mind, where there are mental phenomena, mind-consciousness, things to be cognized by mind-consciousness, there Mara exists or the description of Mara.
“Where there is no eye, Samiddhi, no forms, no eye-consciousness, no things to be cognized by eye-consciousness, there Mara does not exist nor any description of Mara.
“Where there is no ear … no mind, no mental phenomena, no mind-consciousness, no things to be cognized by mind-consciousness, there Mara does not exist nor any description of Mara.”
