SN 7.6

At Sāvatthī.

Then the brahmin Bhāradvāja of the Matted Hair went up to the Buddha, and exchanged greetings with him.

When the polite greetings and small talk were over, he sat down to one side, and addressed the Buddha in verse:

A tangle within, a tangle without:
People are entangled in a tangle!
I ask you this, O Gotama:
Who can untangle this tangle?

[The Buddha replied:]

A wise man grounded in virtue,
Developing the mind and wisdom,
An ardent and astute contemplative,
Can untangle this tangled mass.

Those who have washed away
Greed, hatred, and ignorance—
The arahants, their defilements ended—
For them this tangle is unravelled.

Where name and form —
Its impingement and perception —
Stop without a trace:
It's there that this tangle is cut.

When he had spoken, Bhāradvāja of the Matted Hair said to the Buddha, “Excellent, Master Gotama! …” … And Venerable Bhāradvāja became one of the arahants.
