<human>: My friend who I met recently and felt a romantic connection with immediately has been ordained as a Buddhist Monk. I met him only a few weeks before he was ordained. He wrote this sutta down for me and told me to think about it. Would love to hear your thoughts.

"Those men of old who excelled in virtue,
Those brahmins who recalled the ancient rules,
Their sense doors guarded, well protected,
Dwelt having vanquished wrath within.
They took delight in Dhamma and meditation,
Those brahmins who recalled the ancient rules.

"But these have fallen, claiming 'We recite.'
Puffed up by clan, faring unrighteously,
Overcome by anger, armed with diverse weapons,
They molest both frail and firm.

"For one with sense doors unguarded
All the vows he undertakes are vain
Just like the wealth a man gains in a dream:

Fasting and sleeping on the ground,
Bathing at dawn, study of the three Vedas,
Rough hides, matted locks, and dirt;
Hymns, rules and vows, austerities,
Hypocrisy, bent staffs, ablutions:
These emblems of the brahmins
Are used to increase their worldly gains.

"A mind that is well concentrated,
Clear and free from blemish,
Tender towards all sentient beings—
That is the path for attaining Brahma."

Can you provide a brief rundown of the text in within 3 sentences?
