With Rādha
At Sāvatthī. Then Venerable Rādha went up to the Buddha … and asked him, “Sir, how does one know and see so that there’s no I-making, mine-making, or underlying tendency to conceit for this conscious body and externally for all signs?” “Rādha, one truly sees any kind of form at all—past, future, or present; internal or external; solid or subtle; inferior or superior; far or near: all form—with right understanding: ‘This is not mine, I am not this, this is not my self.’ One truly sees any kind of feeling … perception … choices … consciousness at all—past, future, or present; internal or external; solid or subtle; inferior or superior; far or near: all consciousness—with right understanding: ‘This is not mine, I am not this, this is not my self.’ That’s how to know and see so that there’s no I-making, mine-making, or underlying tendency to conceit for this conscious body and externally for all signs.” … And Venerable Rādha became one of the perfected.
