I considered: ‘This Dhamma that I have attained is profound, hard to see and hard to understand, peaceful and sublime, unattainable by mere reasoning, subtle, to be experienced by the wise. But this generation delights in attachment, takes delight in attachment, rejoices in attachment. It is hard for such a generation to see this truth, namely, specific conditionality, dependent origination. And it is hard to see this truth, namely, the stilling of all formations, the relinquishing of all acquisitions, the destruction of craving, dispassion, cessation, Nibbāna. If I were to teach the Dhamma, others would not understand me, and that would be wearying and troublesome for me.’ Thereupon there came to me spontaneously these stanzas never heard before:
‘Enough with teaching the Dhamma
That even I found hard to reach;
For it will never be perceived
By those who live in lust and hate.
Those dyed in lust, wrapped in darkness
Will never discern this abstruse Dhamma
Which goes against the worldly stream,
Subtle, deep, and difficult to see.’
Considering thus, my mind inclined to inaction rather than to teaching the Dhamma.
“Then, bhikkhus, the Brahmā Sahampati knew with his mind the thought in my mind and he considered: ‘The world will be lost, the world will perish, since the mind of the Tathāgata, accomplished and fully enlightened, inclines to inaction rather than to teaching the Dhamma.’ Then, just as quickly as a strong man might extend his flexed arm or flex his extended arm, the Brahmā Sahampati vanished in the Brahma-world and appeared before me. He arranged his upper robe on one shoulder, and extending his hands in reverential salutation towards me, said: ‘Venerable sir, let the Blessed One teach the Dhamma, let the Sublime One teach the Dhamma. There are beings with little dust in their eyes who are wasting through not hearing the Dhamma. There will be those who will understand the Dhamma.’ The Brahmā Sahampati spoke thus, and then he said further:
‘In Magadha there have appeared till now
Impure teachings devised by those still stained.
Open the doors to the Deathless! Let them hear
The Dhamma that the Stainless One has found.
Just as one who stands on a mountain peak
Can see below the people all around,
So, O Wise One, All-seeing Sage,
Ascend the palace of the Dhamma.
Let the Sorrowless One survey this human breed,
Engulfed in sorrow, overcome by birth and old age.
Arise, victorious hero, caravan leader,
Debtless one, and wander in the world.
Let the Blessed One teach the Dhamma,
There will be those who will understand.’http://suttacentral.net/mn26/en/http://www.accesstoinsight.org/tipitaka ... .than.html
