[858] "Furthermore, Ānanda, when a bhikkhu smells an odor with the nose, there arises the agreeable, there arises the disagreeable, there arises the agreeable-and-disagreeable. He understands thus: 'There has arisen in me this agreeable, there has arisen the disagreeable, there has arisen the agreeable-and-disagreeable; and that is conditioned (saṅkhata), gross, dependently arisen. This is peaceful, this is sublime, namely, equanimity (upekkhā).' In him that arisen agreeable, that arisen disagreeable, that arisen agreeable-and-disagreeable ceases, and equanimity becomes established. Just as, Ānanda, drops of water on a slightly sloping lotus leaf roll off and do not remain, even so, Ānanda, in whomever the arisen agreeable, the arisen disagreeable, the arisen agreeable-and-disagreeable ceases thus quickly, thus swiftly, thus without difficulty, and equanimity becomes established — this, Ānanda, is called, in the discipline of the Noble One, the supreme development of the faculties (anuttarā indriyabhāvanā) regarding odors cognizable by the nose."
