Dutiyamettāsutta
“Cattārome, bhikkhave, puggalā santo saṁvijjamānā lokasmiṁ. Katame cattāro? Idha, bhikkhave, ekacco puggalo mettāsahagatena cetasā ekaṁ disaṁ pharitvā viharati, tathā dutiyaṁ tathā tatiyaṁ tathā catutthaṁ. Iti uddhamadho tiriyaṁ sabbadhi sabbattatāya sabbāvantaṁ lokaṁ mettāsahagatena cetasā vipulena mahaggatena appamāṇena averena abyāpajjena pharitvā viharati. So yadeva tattha hoti rūpagataṁ vedanāgataṁ saññāgataṁ saṅkhāragataṁ viññāṇagataṁ te dhamme aniccato dukkhato rogato gaṇḍato sallato aghato ābādhato parato palokato suññato anattato samanupassati. So kāyassa bhedā paraṁ maraṇā suddhāvāsānaṁ devānaṁ sahabyataṁ upapajjati. Ayaṁ, bhikkhave, upapatti asādhāraṇā puthujjanehi.
Love (2nd)
“Mendicants, these four individuals are found in the world. What four? Firstly, an individual meditates spreading a heart full of love to one direction, and to the second, and to the third, and to the fourth. In the same way above, below, across, everywhere, all around, they spread a heart full of love to the whole world—abundant, expansive, limitless, free of enmity and ill will. They contemplate the phenomena there—included in form, feeling, perception, choices, and consciousness—as impermanent, as suffering, as diseased, as a boil, as a dart, as gloom, as an affliction, as alien, as breaking apart, as empty, as not-self. When their body breaks up, after death, they’re reborn in the company of the gods of the pure abodes. This rebirth is distinct from that of ordinary people.
