Here’s how I heard it: One time the Blessed One was living in Sāvatthi, at Jeta’s Park in the monastery built for him by Anāthapiṇḍika. In the morning the Blessed One got dressed in yellow monks robes, took his bowl and went to Sāvatthi for alms. The Venerable Rahula got dressed in his robes, got his bowl and ran off to follow the Blessed One. And the Blessed One looked back at the Ven. Rahula and called to him:
“Rahula, whatever has form – past, future or present, internal or external, obvious or subtle, despicable or excellent, far or near – all forms should truly be fully seen and understood in this way: ‘That is not me, that is not mine, that is not my self.’ ”
“Really, just forms, Blessed One? Really, just forms, Happy One?”
“Forms, Rahula; and sensations, Rahula; and perceptions, Rahula; and mental formations, Rahula; and consciousness, Rahula.”
