AN 4.213

Akataññutāsutta

“Catūhi, bhikkhave, dhammehi samannāgato yathābhataṁ nikkhitto evaṁ niraye. Katamehi catūhi? Kāyaduccaritena, vacīduccaritena, manoduccaritena, akataññutā akataveditā— imehi kho, bhikkhave, catūhi dhammehi samannāgato yathābhataṁ nikkhitto evaṁ niraye.

Ungrateful

“Mendicants, someone with four qualities is placed in hell as if delivered there. What four? Bad conduct by way of body, speech, and mind, and being ungrateful and thankless. Someone with these four qualities is placed in hell as if delivered there.

Catūhi, bhikkhave, dhammehi samannāgato yathābhataṁ nikkhitto evaṁ sagge. Katamehi catūhi? Kāyasucaritena, vacīsucaritena, manosucaritena, kataññutā kataveditā— imehi kho, bhikkhave, catūhi dhammehi samannāgato yathābhataṁ nikkhitto evaṁ sagge”ti.

Someone with four qualities is placed in heaven as if delivered there. What four? Good conduct by way of body, speech, and mind, and being grateful and thankful. Someone with these four qualities is placed in heaven as if delivered there.”
