Kuta Sutta – A Good Roof
In the Kuta Sutta, the Buddha teaches Anathapindika the importance of protecting one’s mind through wise restraint. Anathapindika was a wealthy businessman and early benefactor of the Buddha and the original Sangha. Anathapindika integrated the Eightfold Path and awakened while continuing to live in the world of commerce free of worldly entanglements.
Anguttara Nikaya 3:110
On one occasion Anathapindika went to the Buddha, bowed with respect for his teacher, and sat to one side.
The Buddha, acknowledging his benefactor, instructed him in the Dhamma: “When un-restrained the mind has no protection. From a mind lacking protection it follows that the body is unprotected and so verbal and mental actions are unprotected, an uncomfortable and disappointing abode. 
“Just as when a house is poorly roofed the house is unprotected. The beams, the walls, the floors, all become soggy. This house is an uncomfortable and disappointing abode.
“In the same manner, from an un-restrained mind, lacking protection, one’s bodily, verbal, and mental actions get soggy and become an uncomfortable and disappointing abode. (Refined) Mindfulness has no lodging and the opportunity for an auspicious life is lost. 
“Friend, just as when a house is properly roofed the house is protected. The beams, the walls, the floors, won’t rot. This house is a comfortable and content abiding.
“When restrained the mind is protected. When the mind is protected bodily, verbal, and mental actions are also protected. A comfortable and content abiding is present. (Refined) Mindfulness is well-established and the opportunity for an auspicious life is present.

If you find benefit here please:
My Dhamma articles and talks are based on the Buddha's teachings (suttas) as preserved in the Sutta Pitaka, the second book of the Pali Canon. I have relied primarily on Thanissaro Bhikkhu’s excellent and insightful translation of the Pali generously made freely available at his website Dhammatalks.org, as well as the works of Acharya Buddharakkhita, Nyanaponika Thera, John Ireland, Maurice Walsh, Hellmuth Hecker, and Sister Khema, among others, as preserved at Access To Insight.
Also, I have found Bhikkhu Bodhi's translations from Wisdom Publications Pali Canon Anthologies to be most informative and an excellent resource.
I have made edits to the suttas from these sources for further clarity, to modernize language, to minimize repetition, and maintain contextual relevance to Dependent Origination and Four Noble Truths.
