THE UNBOUND PERSON IS A BRHAMANA
Yassa param aparam va paraparam na vijjati
Vitaddaram visamyuttam tam aham brumi brahmanam.
He who has for him neither this shore (i.e. the sense bases) nor the other shore (i.e. the sense objects),
and who is undistressed and free from moral defilements,1- him I call a brahmana. 
Kana Mata was a devoted lay disciple of the Buddha. Her daughter Kana was married to a man from another village. As Kana had been on a visit to her mother for sometime, her husband sent a message asking her to come home. Her mother requested her to wait for a few more days as she wanted to send along some cakes for her son-in-law.
- 'This shore' and 'the other shore' are used in the sense of internal and external ayatanas. The internal ayatanas are the sense bases, viz., eye, ear, nose, tongue, body and mind; the external ayatanas are the sense objects, viz., visible object, sound, odour, taste, touch and mind-object. For a true brahmana (i.e. Arahant) there is neither 'this shore' nor 'the other shore'; which means that the senses of the Arahant are calmed, and his passions extinguished.
