Saṃyuktāgama 135. [Second Discourse on Abandoning Doubt]
Thus have I heard. At one time the Buddha was staying at Sāvatthī in Jeta's Grove, Anāthapiṇḍika's Park.
At that time the Blessed One said to the monks … as fully said above, with the difference: “Suppose a learned noble disciple examines these six standpoints for views as not self and not belonging to a self. One who contemplates in this way abandons doubt in relation to the Buddha, in relation to the Dharma, in relation to the Community, and abandons doubt in relation to dukkha, in relation to its arising, in relation to its cessation, and in relation to the path … to be spoken in full up to … makes an end of dukkha.”
When the Buddha had spoken this discourse, hearing what the Buddha had said the monks were delighted and received it respectfully.
